“Saaliha, come with me to the light table,” Evelyn whispers. “I have to show you something!”

Hand in hand, the two preschoolers quietly make their way over to our light table. This darkened corner of our classroom never fails to mesmerize the children with its soft glow and luminous colors.

As the days grow shorter and darker—and the hectic holiday season approaches—it’s the perfect time to engage children in calming investigative play with light and color.

Before we gather around the light table, I dim the lights in the classroom and put on some soft music to create a soothing and tranquil setting for the children, who are often overscheduled, tired and anxious during these busy December days.

“Look!” says Evelyn. “I took a play silk from our dress-up bin and put it on the light table!”

Evelyn moves over to make room for Saaliha at the light table and the two friends immerse themselves in STEAM collaboration, problem-solving and investigation. The girls are completely absorbed in their play—and the learning is enhanced by the presence of a friend and collaborator.

“That’s cool!” says Saaliha. “It makes everything look a little different, but you can still see all of the different colors!”  

The light table allows for open-ended play, where children can experiment and create without strict guidelines. This type of play fosters the development of creativity and problem-solving skills as the children follow their curiosity, devise their own experiments and draw their own conclusions. This child-led play also fosters an investigative mindset, which can lead to hours of exploration and discovery.

“Try this!” Evelyn suggests as she shows Saaliha how to duck under the silk to compare the views. 

The girls experiment with different color combinations and share their theories and discoveries. The light table always seems to spark curiosity and encourages children to ask questions and seek answers.

As more children join the investigative play, they expand their knowledge base by collecting data and adding probability to their investigative skills.

This is a shared space that encourages collaborative investigations. Collaboration fosters communication skills, teamwork and the ability to share ideas with peers.

Children work together to create patterns, build structures and explore different materials—a process that helps foster the development verbal and social skills.

The hands-on nature of these activities promotes a deeper understanding of mathematical principles through play.

Children can investigate fundamental mathematical concepts such as counting, sorting, patterns and shapes on the light table. 

These long play periods extend the learning as the group explores spatial relationships, patterns and sequencing, laying a foundation for more advanced mathematical thinking.

Play at the light table is naturally enjoyable for young children. The combination of vibrant colors, interactive materials and the freedom to explore creates a positive and joyful learning experience that can contribute to a lifelong love of learning. 

Light tables allow children to learn at their own pace, which makes the play developmentally appropriate for every early learner. The children build on their own knowledge and share their observations with others.

When children are making observations and discoveries, they are forming and testing hypotheses. These self-directed learning experiences empower them to continue to explore and investigate beyond the classroom.

So turn on that light table and watch the magic of play and discovery brighten the day! 

Today is one of those magical winter mornings when snow blankets the ground and clings to the trees around our center.  The sun is shining and the world looks so sparkly and irresistible that we head outside in spite of the freezing temperatures.

“Hey! Who has the smiling boot?” Jacoby calls out to the group. He scans the play space, which looks like a snowy white canvas dotted with boot prints.

“Do you have the smiling boot?” he asks Maria.  

Maria looks confused as she glances down at her boots. “No, my boots are pink.” 

“No, no…on the bottom!” Jacob points to her boots. “Does your boot have a smiling face on the bottom?” 

Even I am confused by Jacoby’s question—until he points to the clue in the snow. 

“Look!” he declares. “Somebody has a smiley face on the bottom of their boot.”

Ah-hah! Indeed, we do have a smiley face boot print staring up at us from the snow-covered ground. Well, this will warm us all up!  Let the STEM investigation begin!

After a fresh snowfall, it’s so much fun to find and follow animal tracks. But we’ve never really paid attention to the patterns on the soles of our boots until now.

One by one, Maria and Jacoby begin to check the bottom of each friend’s boot. This simple moment of exploring patterns leads us to measurement, reasoning and comparing attributes.

Young children instinctively seem to notice attributes. It may be the shape, size, color, length or some other characteristics of an object, such as today’s smiling boot face.

Children develop their understanding of matching and patterns through experience. Because it’s difficult to consider a lot of attributes at once, children often begin creating sets by finding exact matches.

When children create pairs of boots or find an exact match to the smiling boot face, they are creating sets of items that are exactly alike. Maria and Jacoby are using rudimentary math, science and engineering skills as they observe and ask questions—all while solving the smiling boot print mystery!

Suddenly, everyone is stomping their boots and comparing and analyzing the shapes and patterns that their boots are leaving in the snow.

“I have zigzags!” announces Liam.

Sure enough, as we all run over to look at Liam’s boot print in the snow, we see row after row of zigzags.

“They look like mountains!” laughs Rokia. “That’s so cool!”

 “I have rectangles!” announces Rachel. “If I turn around, it looks like a house with a roof. Look!  See, at the bottom of my boot print?”  

Our focus is now very intentional and the mood has shifted from playful curiosity to deep observation and concentration. 

This is what child-led learning looks like. For those of you who believe that “child-led learning” can only lead to chaos, I urge you to put on your winter wear, head outside and see how effective and wondrous it can truly be.

“I have diamonds!” shouts Julio, “Oh and triangles at the top and bottom. Wow! Look at my boot print, it has really cool patterns.”

We are working on spatial reasoning, direction and positional vocabulary. This is the deep learning that takes place when children have ample time to explore and investigate.

Every day, children learn something new.  Every day, they deepen their understanding of STEM principles and share their insights and theories with their fellow STEM explorers.

Time is the key to deep learning!

“I have snakes!”  Josie shouts.

“Snakes?” 

Everyone comes running to see the newly discovered boot-print pattern. And, yes indeed, Josie’s boot print really does look like snakes.

But Isaac sees it differently. “I think it looks like waves,” he counters. “You know, like when you throw a rock in the river and it makes those lines?”

Then five-year-old Maya reorients the group to the smiley-face boot prints that started the morning’s STEM investigation.

“Where did that smiley face boot come from?” she asks, putting an end to the snake-shape and wave-shape discussion.

“I don’t know!” retorts a frustrated Jacoby. “That’s what I am trying to figure out!” 

“No, I mean, where did the smiley face boot print start?” Maya clarifies, assuming the role of lead investigator. “Where did you find it? Did you follow it, like we followed the cat paw prints last winter?” 

Jacoby pauses and I can see the wheels turning as he considers Maya’s questions. This is a lightbulb moment when the children suddenly recall a forgotten game from winters past. We have plenty of wandering cats in our neighborhood. For years, we have engaged in follow-the-cat-print expeditions on snowy days, following the tracks and trying to figure out the exact route that the cat took and why. Today has ushered in a new season of snow—and now we are rediscovering the game all over again.

Five-year-old Maya has had a few more years of brain development and a few more years of winter play, so she has retained more memories of those snowy-day games than the younger children who started the smiling boot print investigation.

Suddenly we are tracking movement, direction and the changes in how the boot print is left. We don’t have paper and pencils to collect data outside today, but our friends are forming hypotheses and making deductions as they piece the clues together and abandon the ideas that don’t pan out.

Maya continues as the lead investigator. “Look at the size of this boot track. It’s much bigger than our boots. See? I think it’s an adult boot print. Look how far it is between the foot prints. It takes me three steps to their two steps.”

“Maybe it’s the mail carrier,” suggests Lois.  “She brought a package to the door yesterday.”

“It can’t be the mail carrier,” reasons Maya. “She doesn’t walk on this side of the center.”

“It must be a parent!” shouts Jacoby. “Who has a parent with a smiling boot?”

The question is met with dead silence. No one knows the answer.

Suddenly, Maya turns to me and asks, “Do you have a smiling boot? You are an adult.”

Much to my disappointment and the chagrin of my young friends, I am not the owner of the smiling boot. We are getting cold and our investigation has hit a dead end. We decide to go indoors and warm up with some hot cocoa and banana muffins.

At pickup time, the children check the boots of every parent for a smiling face, but no one has the matching boot. Many weeks later, we discover that the smiling boot belongs to a grandparent of one of the children at our center. By then the thrill of the hunt is over. But the learning has not been lost. A great morning of STEM investigation is tucked away safely in the developing brains of our early math explorers.

“One, two, three, flip!” 

“I win!” shouts Matif.

Remember playing War as a child? It’s simple and fun and it teaches young children how to win and lose without a lot of drama.

I love playing cards with young children because that little deck helps foster the development of early math and social-emotional skills in a big way.

When I play War with very young children, I often pull out the face cards and any card higher than a six. Depending on the ages and developmental levels of my students, I may even pull out the aces because it’s too difficult for young children to associate the letter “A” with the number “1.”

Start by dealing the cards evenly between all of the players, stacking the cards face down in front of each child. 

No peeking allowed!  On the count of three, each player will flip the top card over into the center of the table, face up.

“One, two, three, flip!”

A chorus of young voices chants in rhythm as our game continues.

“I have a five,” shouts Mable. “That’s bigger than your two, so I win!” 

Compare the cards played. The highest card wins the hand. The winner takes all of the cards played in the round and adds them to a new stack of “won” cards. 

One, two, three, flip!”

“Ah, you both have a six! War!”

When there’s a tie between the two highest players, you have a “duel.”

To play a duel, the two players each place three cards in the middle of the table, face down. Then they each lay down another card (the fifth card for this round). This card should be facing up. The highest card wins, and the winner takes all of the cards from this round and adds them to a new stack.

“One, two, three, flip!”

I watch as a four and a three get turned over by the players in the duel.

“Ah, you won all those cards!” says the child with the losing hand. “Lucky you!” 

When children are playing cards, this is a great time to observe their number sense. Can they identify the numbers by name? Can they determine which number is higher? Can they follow the rules?  When the cards match, can they count out the three additional cards that they will need for a duel?  

Play until your main stack is gone and then count up how many cards the players have in their stacks of “won” cards. The player with the most cards wins. Once the children have mastered the cards through the number six, I will add the sevens and eights back into the deck. Later, I will add in the nines and the tens.

Many children will be able to play a full game of War by the time they reach kindergarten—face cards included. Keeping it simple in the beginning is a great way to assess your students’ number recognition skills and value development.

As children play this deceptively simple game, they are developing their number-recognition skills and beginning to grasp concepts such as number value, greater than and less than.

They are also learning important life skills such as how to follow rules, take turns and take their turns quickly without making the other players wait too long. That’s a lot of learning for a game that fits in your pocket! 

We also want to teach children how to win and lose graciously. I love playing War because it’s a game of chance and everyone has an equal chance of winning. Because each round has a winner, we are practicing the win/lose concept over and over again in rapid succession. There isn’t time for the winners to jump up and do a victory dance or the losers to break down and get weepy. The same child will not win every round, which gives every child many opportunities to practice good sportsmanship.

There’s a reason that children have enjoyed playing War for generations. It’s fast and fun and a bit addictive. So grab a deck or two, play a few rounds with your early learners and call it your math curriculum for the week. You’ll be teaching invaluable life lessons along with those early math skills!

“Do you know about our Magic Tree?” four-year-old Rowan asks Alex. She pauses dramatically before passing on the secret of the beloved old tree that has long been a source of delight and inquiry for the children in our early learning program.

“Watch, Alex!” she instructs. “I will push this stick into the tree, way up here, and say ‘Hocus Pocus.’ Then I can pull the stick out of the tree way down here at the bottom!”

Alex is the perfect audience for Rowan’s magic trick. I watch as the rest of the gang joins in the fun to demonstrate the tree’s “magical” abilities, much to Alex’s amazement.

“See?  I put the stick in this circle hole. It’s a hollow tree! There isn’t any tree inside, it’s just a hole!” explains Rowan. “And then you can pull it out down here at the bottom of the tree!”

“The tree is hollow?” Alex repeats in wonder, moving closer to the tree to peer into the hole.

“Yep, it is!” exclaims Owen, who has just joined the gaggle of STEM explorers gathered around the tree. “So you can just push your stick in and say the magic words and pull it out down here!”

Our Magic Tree has evoked wonder and curiosity in the entire gang, sparking a STEM investigation that helps lay the foundation for later math, science and engineering learning. Nature has provided the ultimate learning tool and transformed a moment of outdoor play into an exploration of the concepts of spatial relationships and geometry.

As the children explore the Magic Tree, each moment of learning comes naturally and at each child’s developmental level. When the older children share the secrets of the tree with younger learners, relationship building and trust building add to the magic of the moment.

An understanding of spatial relationships helps children talk about where things are located. Physical, hands-on play like this helps build a child’s mathematical vocabulary in a natural way that is easily understood. When a child can push a stick through a cylinder shape, the concept behind the word through is easier to grasp.

So we allow the children to investigate by pushing sticks down the circle hole, through the hollow part of the tree and out again through the bottom of the trunk. This exploration of spatial relationships—which leads to an understanding of where objects are in relationship to something else—is an essential building block for later math learning.

Children need to learn the language of math to think through and solve their math challenges and then communicate their thought processes to others.

When children play and experiment with sticks and hollow trees with their friends, they learn how to problem-solve and put their thoughts into words. This strengthens their understanding of early math concepts as they use math vocabulary words repeatedly throughout their play.

Geometric shapes are a kindergarten common core standard. When children actually play with (and within) these shapes as they explore the inside of the hollow tree, the learning becomes deeper, more intentional and more relevant.

“I think it’s stuck!” yells one child.

“Wait! How many sticks are in there?” asks another.

We begin to get a better sense of measurement as we visually estimate the length of a stick that will fit into the hollow tree and come out the other side.

Opportunities like these are rich in learning, creativity and teamwork as we share theories and develop hypotheses about stick sizes and shapes, as well as angles of insertion, that will result in the “magical reappearance” of the stick at the bottom of the tree.

Problem-solving play helps children develop foundational skills that will be used in math learning in the years to come. Our gang of STEM explorers is busy making predictions, gathering data, studying cause and effect and organizing their information to try something new. We are knocking out those Illinois Early Learning Standards by the minute!

“Can we make the stick go UP the tree?” wonders Linnea.

“I’ll try!” Rowan chimes in.

Hands-on learning also enables children to take their understanding to a deeper level, so that they can analyze the information that they have collected and then apply this knowledge when they create their own experiences.

The children’s enthusiasm for experimenting with the Magic Tree is contagious. When we let children learn through play, movement and trial and error, we lay the groundwork for the kind of deep learning that builds new neural connections. These are the moments that inspire our early learners to investigate the possibilities.

When we introduce children to the vocabulary of math, we are building a foundation for future math success. This early math website has a fabulous glossary of math vocabulary words.

Introduce these vocabulary words into moments of investigative play and you’ll not only see but “hear” the connections being formed in the brains of your budding mathematicians.

If you don’t have a magic tree nearby, a large box can create the same kind of magic. Cut two holes at different heights on opposite sides of the box and bring in yardsticks or other long objects. This can also be done on a smaller, individual scale with oatmeal boxes and rulers or pipe cleaners.

The possibilities are endless, so let the STEM magic begin!

“Hey, Evelyn!  Go get your cell phone and meet me at the stumps!” calls Noa.

My head whirls around as I check the classroom to see if a cell phone has actually made its way into school today. Then I see Evelyn running to the basket of dominoes to get her “cell phone.”

Whew! Instant relief and a touch of humor added to my day.

Dominoes have been around for centuries. They’ve been used for all sorts of games around the globe. We have baskets of dominoes scattered around the classroom. We use them for everything from building and matching to chain reactions. I’m fairly sure that we’ve never played an actual game of dominoes with these versatile learning tools!

I love these little blocks. Whatever the game, dominoes are always a Developmentally Appropriate Play (DAP) item, regardless of the ages of the children playing with them.

This morning’s “cell phone” incident got me thinking about Developmentally Appropriate Practice.

We need to trust that the teachers who work with young children on a daily basis know what’s appropriate for these children and understand how they use their materials.

Dominoes may not be designed for toddlers and preschoolers—and may even be considered to be Developmentally Inappropriate if used as intended.

Yet, by adding dominoes to our play areas and using them as manipulatives and loose parts, we can expose our early learners to a wealth of STEM learning opportunities such as building, counting, matching and even dramatic play.

Whether we’re building with our dominoes or standing each domino on end to create a chain reaction, we are laying the foundation for strong math and science skills.

This is when parents and administrators may misconstrue active learning for mere play.

When this happens, it’s our responsibility to help parents and administrators “see” the learning that is taking place. Show them how their children are developing spatial skills and an understanding of concepts such as “location” and “ordinal position.”

“Wow, Michela, your tower is getting really big!” Jameson stops to watch as Michela carefully adds another block to her structure.

Jameson has been struggling to build a tower that rivals Michela’s in height. “My tower is too wobbly,” he moans. “It keeps falling down. It’s impossible!” He stomps his foot in frustration and crosses his arms over his chest.

“You need to go very slow, like this,” responds Michela without taking her eyes off of her tower.

Michela is demonstrating the practice of science and engineering. We have geometry unfolding before our eyes as Michela uses symmetry, visualization, spatial reasoning and geometric modeling to solve problems such as balance and continuity.

By observing and asking questions, sharing ideas and solving problems, the children are working as a team to build a greater understanding of what works and what doesn’t.

This is a form of early data collection. If you are studying force and motion, a domino chain reaction is a great activity to demonstrate potential and kinetic energy.

I watch as four-year-old Thompson counts the pips (dots) on his dominoes and begins exploring concepts such as quantities and attributes.

Across the table, two-year-old Joseph is learning rote counting skills and gaining a rudimentary sense of one-to-one correspondence. By playing with the dominoes, he is also seeing the grouped pips (dots) in number formations that he will continue to see throughout his life.

I watch as an older friend mentors Joseph. In no time, Joseph is matching attributes—sometimes by pattern and sometimes by color. This is math!

We are exploring concepts such as “matching,” “same and different” and “up and down.” We are counting and beginning to understand numbers and number names. We are comparing quantities, subitizing and measuring objects and quantities. We are identifying common attributes, patterns and object relationships.

We are engaged in deep, hands-on, child-led play—without worksheets, themes or circle times. This is developmentally appropriate learning!

By providing more opportunities for children to explore, discover and investigate through active play, we are meeting one of the most important goals of early childhood education.

Invest in a variety of materials to meet the needs of children with different learning styles. It’s worth the cost. Think of it as an investment that will pay off in the future success of your early learners.

So grab those dominoes off of the shelf, place them in a basket and let the STEM learning begin!

Enjoy!

I recently grabbed our dusty box of beanbags off of the top shelf of the closet and took the beanbags outside. We rarely played with them indoors, so what was I saving them for?  If a beanbag gets lost or forgotten under the plants and soaked in the rain, who cares? At least it has been played with.

Now that the beanbags have been relocated to our outdoor play space, they have been used daily over the past few weeks. Recently we created a new beanbag game that laid the foundation for later STEM learning.

We currently have a full group of children who can pump on the swings, which is great—unless you have more children than swings, like we do. So I brought out the bucket of beanbags and placed it on the edge of the sidewalk. 

Then I picked up a beanbag and gently tossed it in the direction of my swinging friends. The kids loved the idea and it was GAME ON!

Now mind you, the swings were a good 12 feet away from that sidewalk—far enough to ensure that none of the children would be strong enough or accurate enough with their beanbag tosses to actually harm a friend.

“Hit me! Hit me!” hollered the members of the swinging gang.

“I want to play!” shouted the rest of the gang.  AYE YAE YAE!  What had I started?

What I had started was a new game that quickly became a favorite. No one has been injured, few have been hit and the cooperation and turn-taking is incredible!

Our rules were simple:

1. Throwers had to stay on the sidewalk.
2. No creeping up on the swingers.
3. Only throw one beanbag at a time.
4. When all beanbags have been thrown, yell, “SWITCH!” and the swingers must stop.

When the swingers stopped that first day, there was a mad rush by all to pick up the beanbags and put them back into the basket for the next round. WHAT in the world? I NEVER see this type of energy and enthusiasm during usual pickup times!

I encouraged the new group of throwers to take a water break to give the new swingers time to get up to speed before the throwers started aiming at their targets. And then we repeated the cycle for a good 20-30 minutes before the children exhausted themselves from all of their throwing and pumping.

We had overhand throwers and underhand throwers. I watched as they tried different techniques and shared theories with each other on the best time to throw the beanbag depending on where the swingers were in the air. This is physics! This is math and geometry and plain old fun!

Investigations into physical science and engineering through this type of play give young children a chance to explore and control physical phenomena and develop a practical understanding of the laws of physics— all while giggling with their moving-target friends.

This activity also teaches children about risk-taking and trust building. You trust that your friend won’t hurt you, but you definitely take the risk of possibly getting hit. Scary but fun!

As the game evolved, new ideas were added to the play. Sometimes children called out the number or  letter printed on the beanbag or grabbed specific colors. One three-year-old consistently looked only for beanbags labeled with letters that had meaning to him: the first letter of his name or the names of his two siblings. (I later found three beanbags labeled with those letters hidden in a secret corner of the yard. Ha!)

Physically, our beanbag throwers were building up the muscles of their dominant hands, which they will use in future academic settings. They were also working on STEM concepts such as distance, accuracy, speed and force. We throw these wonderful science words into their play to build up their STEM vocabulary and lay the foundation for a deeper understanding of scientific concepts. Meanwhile, our swingers were  focusing on the trajectories of the beanbags headed in their direction and making predictions about when and where they would hit, while strengthening their core muscles for future desk and circle time.

OH, you want learning standards? We’ve got those covered too. We count, subtilize and build our math vocabulary. We measure and estimate distance. We make predictions and modify those predictions based on experience. We use our science skills to explore the physical properties of objects and experiment with force and motion. The list goes on and on and there are so many ways to adapt this game. So grab your beanbags, head outdoors and let the playing and learning begin!

“Will the children be kindergarten ready if they spend their days playing outside?”

As educators, we are often asked about kindergarten readiness by nervous parents who want to give their children the best possible start in life.

It’s important for parents—and educators—to understand that there are endless opportunities for deep learning when children are connected to nature. Young children learn primarily through their senses. The natural world—with its stimulating and constantly changing elements—provides the ultimate sensory learning environment.

When children explore the world through sensory play, they are actively building new neural pathways, which is crucial for brain development. When we slow down enough to observe this process, it’s easy to see the learning that takes place, and the social skills that are being developed, as the children collaborate on projects in the great outdoors.

On an unusually warm day in May, the boys in our program are busy building a large castle in the sandbox. This may look like nothing more than sandbox play, but there’s some deep learning going on here as our castle architects lay the foundation for future academic success.

“We should build a moat!” declares Joshua.

“Yeah, a moat!” agrees the gang. “We definitely need a moat!”

With these words, the digging begins. Before long, the castle builders decide that it’s time to add water to the moat. We have plenty of buckets at our center, but today most of the buckets are already in use.

Looking around for a way to transport the water from the pump to the sandbox, the boys settle on a nearby piece of fabric from one of their forts.

We’re all hot, tired and likely a little dehydrated at this point. A glance at the clock tells me that it’s almost closing time. But who am I to redirect the boys by pointing out the empty bucket next to the fence?

I watch as the boys carefully stretch the material out and center it beneath the pump spigot to catch as much water as they can. Asa begins pumping and, to my astonishment, the fabric holds the water without any leakage.

WHAT in the world?  I’m marveling at this unexpected development when it occurs to me that the cloth I’d purchased from the resale shop is actually a waterproof fabric used in hospital settings.

When I ask the boys if they were aware that the fabric was waterproof when they grabbed it, they respond with a question of their own: “What does waterproof mean?”

I try to explain that waterproof means that the water will not flow through the fabric. But there are times for discussion and times for action—and the boys are already focused on the next step in their plan.

First, they gather the corners of the cloth, taking care to keep the water from gushing out the sides. Then they make their way gingerly across the yard to the sandbox and carefully place the fabric in the moat.

I realize at this point that the boys had deliberately ruled out the use of buckets because they needed a flexible, waterproof liner for their castle moat.

They had assumed that the fabric they chose would hold water and, at the same time, conform to the shape of the moat. Wow! They were way ahead of me!

The boys did eventually make multiple trips to the pump to fill some buckets and add more water to the moat. But they knew that the bucket wasn’t the best tool for the initial phase of moat construction. Silly me!

This is just another example of the importance of giving young children sufficient time to engage in deep play and problem-solving (without any interference from those of us who think we have all of the answers), as well as the importance of loose parts in creative play.

Look at the delight on their faces! Okay, so the castle architect on the far right in the photo below seems to be grimacing at the weight of the load, but the other two look pretty thrilled with the success of their mission!

When we look at children playing in sand, what are WE missing? They are busy designing, creating, collaborating and communicating. They are adding and subtracting, working with shapes and molds and inclines and declines. They are adding water to change the nature of their building material. They are using spatial awareness and math and science vocabulary. They are theorizing, hypothesizing and collecting data. They are engineering and deepening their knowledge—all while playing in a box of sand!

This is the ultimate in STEM learning. Give them as much time as they need. Let them play. Add fabric to your play centers. You never know where their outdoor play will lead them—and what YOU may learn in the process!

“Look everybody! It’s a luna moth!” Rowan’s enthusiasm for any insect on the planet always keeps us on our toes, but today’s discovery has everyone jumping for joy.

When May rolls around, we are often blessed with the arrival of a luna moth on our classroom’s backdoor screen. Upon landing, the luna moth clings to the screen, affording us hours of enjoyment as we get a close-up look at this lovely winged creature.

Luna moths are nocturnal. Like many moths, they are attracted to light, which is why they are often found on screen doors beneath porch lights. Luna moths are easy to identify by their white bodies, long pinkish legs and large, translucent lime-green wings.

Our back door gets a lot of use, so whenever I find a luna moth clinging to the screen, I joke that there are much more peaceful places for this winged creature to stop and rest awhile. But I am always thankful that Mother Nature has blessed us with this learning opportunity.

Today’s luna moth discovery has set our curriculum in motion, with Rowan as our guide. “See those big, beautiful eyespots and that long tail?” she asks. “Those eyespots will trick predators into believing the moth is bigger than it really is.”

When Rowan asks if we can measure the luna moth’s wingspan, we carefully measure the width of its wings. Four-and-a-half inches—almost five!

“Will it bite me?” asks four-year-old Parker.

“No,” laughs Rowan. “It doesn’t have teeth. It doesn’t even have a mouth! This luna moth will only live for seven days. It doesn’t drink or eat. It is only alive to make new baby moths.”

This is pure preschool science—and the children love it! The rest of our day will be spent discussing luna caterpillars as Rowan continues to educate us. At nap time, we will bring out photos of other luna moths, as well as books. Our favorite book at the moment—Beauty the Luna by Julia Welch and Jymann Merritt—is a beautifully illustrated story about the life cycle of the luna moth.

In the coming weeks, we’ll be on the lookout for the luna moth’s eggs: tiny white ovals attached to leaves with a sticky brown adhesive coating.

     
  We’ll also be keeping an eye out for luna moth caterpillars (below).

Rowan’s love of insects is likely due to the influence of her mother, an associate professor of biology who studies insects. Lucky us! We have our own entomologist just a text message away!

Rowan’s mother observes our luna moth over the course of the week and alerts us when the moth is nearing the end of its life cycle. She gently removes the moth from the screen door and guides our young learners through a close-up investigation of the moth’s anatomy.

We count legs, antennae and eyespots. We observe the luna’s markings and compare them to different shapes we’ve learned about. Each child has a chance to hold or touch the luna moth before Rowan’s mother encourages the moth to fly to a more peaceful haven for its final hours.

Last September, we received an email that a graduate of our program (second from right in the photo above) had found a luna moth caterpillar and created a habitat for it with a repurposed Ikea clothes hamper.

As the luna moth caterpillar munched on a meal of walnut, hickory and birch leaves, this junior entomologist told her family that, when threatened by a predator, the caterpillar would rear up on its hind legs and make a clicking sound before puking out a bad-tasting liquid. (We often find that the grossest facts are the most likely to be retained by little brains.)

Within days, the caterpillar had spun a cocoon inside the hamper. Leaves and small branches are often woven into luna moth cocoons to camouflage the cocoon and protect the vulnerable larvae as they metamorphose into moths.

This particular luna moth caterpillar spun its cocoon on the underside of the tag in the hamper below!

Then the waiting began. Caterpillars who cocoon early in the season generally emerge as moths after three weeks, but many weeks passed without a metamorphosis. The hamper was put away for the winter and the family assumed that their luna caterpillar had died.

When spring arrived, the family pulled the outdoor play items out of storage and returned them to the yard (including the hamper—cocoon and all).

On May 20, a full eight months after the caterpillar had spun its cocoon, a luna moth emerged! What happened? It turns out that, if the caterpillar spins itself up in a silken cocoon in late autumn, it “overwinters” and does not emerge until spring.

Opportunities like these may crawl or fly into your classroom on any given day. This is one of the great joys of early childhood education. When STEM opportunities arise, put your planned curriculum on hold and take advantage of the rich learning environments that are literally right outside your door. Incorporate math into the learning experience as you introduce concepts such as size, shape, probability and data collection. Tap into technology for a wee bit of research. Kids LOVE facts that they can retain and share with others. Meet your early learning standards for science when you add topics such as weather, seasons, earth science and life science.

Sightings of luna moths signify new beginnings. But there is a bittersweet symbolism in the arrival of these magical creatures in May, just as our oldest students are about to leave us and move on to kindergarten in the fall.

Nonetheless, the arrival of a luna moth brings endless opportunities for STEM investigation and exploration. Keep your eyes peeled for this magical creature during the month of May, and let the learning begin!

“LOOK!” screams a four-year-old with such joy that we know this isn’t a garden-variety “I want to share something with you” moment.

As the gang rushes to her side, they come to a complete standstill, frozen in awe.

Oh happy day! Some kind souls have shared a fort with the community! There before us stands the most wonderful teepee-shaped fort that we have ever seen. Forts have been popping up all over town this year—and I couldn’t be happier about this trend.

This 14-foot high monument has sparked wonder and curiosity in all of us. We have stumbled upon a STEM adventure! This is math, science and engineering play that allows the learning to come naturally and at each child’s developmental level. This is also sharing. It teaches children that our community creates beautiful spaces to be enjoyed by all.

“Who lives here?” asks Liam as he bravely ventures closer.

“Can we go in?” questions three-year-old Madison, not sure that she really wants to.

We do go in, and the investigation into fort building sets us in motion for the day. Do you remember building forts when you were a kid? Did the memory of that fort just resurface? If it did, you retained that memory and are likely able to build another.

These are the moments that we like to create for our early learners. Hands-on learning enables children to take their understanding to a deeper level so that they can analyze the information that they have collected and then apply this knowledge when they create their own forts.

After giving everyone a turn to observe and discuss the masterpiece in front of us, we take a good hard look at the fort and investigate how it was constructed so that we can build a fort of our own.

We discovered this fort (above) while hiking in our neighborhood.

“I think this fort was started from that fallen branch!” Harper hypothesizes.

This leads to closer observation as we determine that this fort has sides that were built with sticks ranging in size from large to small. By leaning them against the main branch, the architects made the fort longer and wider. We begin to get a better sense of measurement as we visually estimate the length and width of the fort.

We always add a few sticks or branches to any fort that we discover, and today is no different. The older children quickly begin to add branches—an activity that reinforces our perception of the fort as a communal structure. When our younger learners hesitate, we reassure them that they really can’t go wrong by adding a stick or two.

“It looks like a triangle!” shouts Elizabeth. This declaration leads to an animated discussion about shapes and ways to incorporate doors, windows and other shapes into our fort.

We have a geometry class happening before our very eyes! We are looking at two- and three-dimensional shapes and using visualization, spatial reasoning and geometric modeling to solve problems.

These are opportunities that are rich in learning, creativity and team building. We share theories and develop hypotheses about the number of people it might have taken to build the fort, how they got the biggest branches up so high and how they created a base to stabilize the entire structure. We also examine the bottoms of the branches and hypothesize that they were probably broken off during a storm, rather than cut cleanly with a saw.

We know that our forts won’t look like the ones that we’ve encountered. We’ll have to use whatever materials we can find in our own play spaces. But our observations give us a better understanding of the fundamentals of fort and teepee construction. These found structures are the spark of inspiration that we need to design a fort of our own!

It’s time to bring out the assessment chart because this gang is on fire! This playful experience in engineering involves concepts such as angles, inclines, balance and elevation. When we let children learn through play, movement and trial and error, we lay the groundwork for the kind of deep learning that builds new neural connections.

Once the seeds are planted, the children often continue to develop their fort-building skills in our program or in their own backyards.

When the Midwest experienced a rare derecho in August 2020—and every house in our area suddenly had a backyard full of branches—our students immediately began collecting the fallen branches to build forts in their neighborhoods.

They had joined the community-wide fort-building movement!

Notice the similarities? By giving our children long periods of uninterrupted time to play and investigate, we empower them to build their own forts and develop new STEM skills and insights that they will be able to transfer to worksheets when the time is right.

When our students returned to our program this fall, we began napping outdoors on a daily basis. Not surprisingly, when a parent suggested a weekend nap to their child, the child insisted on napping outdoors—in her fort. When children build structures, the joy comes not only from the building but from returning to this place that they have created by themselves, for themselves.

These are the moments when I thank our anonymous community of fort builders for “planting the seeds” of fort building with our young learners. These industrious fort architects may be 12 years old or 90 years old. They may be building these impromptu structures to offer protection from the weather, bring joy to others or simply provide a peaceful place for fellow community members to commune with the natural world.

These lovely forts are gifts of time, hard work and beautiful design that bring science, math and engineering into the lives of our youngest citizens.

Thank you for making so many moments of STEM learning possible through play with the children of our community! You inspire all of us! Thank you! You are truly changing our world!

“AUGGGHHHH!” I hear screams, a crash and giggles galore.

The joy of Magna-Tiles® has returned to our ever-popular window-stacking play. When these colorful magnetic tile mosaics come crashing down from the window frame, the children respond with laughter and joy. By contrast, the collapse of three-dimensional block formations often elicits groans and tears.

Something about the suspense of the build (and the challenge of stacking the magnetic tiles higher and higher without triggering a collapse) keeps the children coming back to this activity time and time again.

For anyone unfamiliar with Magna-Tiles, they are magnetized tiles of different shapes that can be used to build the most amazing creations. We have purchased other magnetic block sets, but the children had difficulty figuring out the polarization or were frustrated by the lack of versatility. Ultimately, those more expensive sets were abandoned to collect dust in a corner while the children spent endless hours playing and learning with the Magna-Tiles.

Is there a more perfect block than a Magna-Tile? If I were stranded on an island with a group of preschoolers, this would be on my top-ten list of must-have learning tools. Heck, it would be on my top-three list. These are, without a doubt, the favorite block in our program. What’s not to love? Magna-Tiles build confidence and fuel hours of creative play. Our only problem with Magna-Tiles is that we never seem to have enough!

I read somewhere that you know you have enough blocks when there are still blocks on the shelves. I’m still not sure I have enough Magna-Tiles on any given day, and I always find myself purchasing more. (Full disclosure: I often purchase PicassoTiles, which are less expensive, equally rugged and nearly identical to my original Magna-Tile set. So, if your program is on a budget, don’t hesitate to buy this less expensive set.)

Magnetic tiles are a STEM classroom delight. We have math opportunities with shapes and colors, counting, blending colors, angles and geometry galore! We have science and engineering as we explore different designs and building techniques. The magnetic feature opens doors to design and construction options that regular wooden blocks cannot provide.

“What color is your tree?” Harrison asks his best friend, Jack, as they use their magnetic tiles to change the colors of the scene outside our window.

The collaboration continues as the two boys follow their creative impulses and develop their ideas.

Then Jack proposes a new challenge. “What if we try a triangle this time?”

The boys determine that the results will be the same regardless of the shape. I am convinced that the children’s understanding of different shapes has been greatly enhanced by the use of these magnetic tiles. Magnetic tiles are the perfect educational tool for teaching all things geometric!

I also love to observe the children as they engage in problem-solving when they are confronted with a shortage of large square magnetic tiles. They quickly determine that they can create the same shape with four smaller magnetic tile squares.

Magnetic tiles also lay the foundation for an understanding of sets and quantities, as well as concepts such as location and ordinal positioning as the children expand their STEM knowledge and vocabulary.

“Jack, do you think we can add this square and it won’t fall down?” asks Jack’s twin sister, Eve, who is working through her predictions and collecting data on what works and what doesn’t.

I watch as Eve gingerly pries the corner of the bottom tile away from the window and triggers a structural collapse that brings all of the magnetic tiles tumbling down.

This investigation of “What happens if…?” is met with delight and infectious laughter from Eve’s peers as the building collaboration starts all over again.

“If we add this triangle to the top, the trees will turn green and look different from the red trees down here.”

Jack and Eve continue to pursue different avenues of learning with the tiles. One minute they are investigating colors and the next they are observing patterns or determining which shape should be added to the mosaic.

I’ve noticed yet another benefit of our window-frame magnetic-tile mosaics: The activity often brings children together who don’t naturally play side-by-side.

In other words, this group endeavor builds community. I am not sure if it’s a team effort of US versus the WINDOW BLOCKS or if it’s simply the contagious joy of the activity that makes everyone want to join in the fun.

When the temperatures drop below zero for days on end, I know that I can count on our magnetic tiles to lighten the mood and enrich our learning through play.

One more note: I have been known to remove the magnetic tiles from our play on occasion.

Why? Because I believe that magnetic tiles are so easy to use that they create “lazy builders.” This is just a personal theory of mine, but I’ve seen it play out over and over again. Sometimes the children in my program need to be pushed out of their comfort zone.

I do this by pulling out my wooden unit blocks, which require the children to perfect the balance and symmetry skills needed to build a stable block tower.

When those wood towers fall, I remind my wee ones that they are great builders and then I help them start building again from the foundation up.

When I rotate the magnetic tiles back into our play after a period of going “back to basics” with the wooden blocks, I nearly always notice that the children’s building skills have improved.

Try it and let me know your results. Happy building!
