“Look!” squeals three-year-old Eleanor. “I can pick up these two balls! It’s magic!” Have you ever seen young children playing with magnets? The “magical” properties of magnets never fail to captivate early learners and spark a play buzz! Children learn by investigating, observing and figuring out how things work. Magnets fuel that curiosity in […]
Rock balancing or CAIRNS has found its way into our play again this week! Stacking and balancing rocks encourages math and science investigations that are always developmentally appropriate. My adrenaline starts flowing and a smile grows on my face when a two-year-old child exhibits an innate sense of how to balance many more rocks […]
“I found GOLD!” squeals Laura. Four little friends are quick to join her in the latest gold rush in the sandbox. In the wee hours of the morning, often when the sun is barely above the horizon and the coffee is still being brewed, gold will magically appear in our sandbox. Spray-painted rocks that […]
“Look! The people blocks are in a line and they crash at the bottom, just like when we play on the slide!” This is a lightbulb moment as Evelyn transfers knowledge gleaned from a previous play experience into her current hands-on learning. A chain-reaction domino fall during today’s block play reminds Evelyn of […]
“Look! The snow packs! Let’s make a snowman!” Today’s sunshine and rising temperatures have transformed yesterday’s powdery snow into packable fun—ushering in an afternoon of playful math and science learning. These are the times when I love to pull out my camera to document the many foundation-building moments that find their way into our play. […]
” Hey guys! Look over here! My magnet sticks to the bike!” On this warm November morning, our magnetic wands have brought STEM learning to our outdoor classroom. By leaving the other magnetic materials behind, I am hoping to encourage the children to harness their curiosity and creativity for other forms of magnetic exploration. […]
“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 […]
“I see the daddy cardinal, do you know where the mama bird is?” Four-year-old Noah, binoculars in hand, is busy counting birds in our outdoor classroom. Are you aware that the annual Great Backyard Bird Count is coming up later this week? This is a great opportunity to create a bird-watching station and knock out […]
“Hey, Hudson! How did you do that?” Eleanor is amazed at Hudson’s success as he races a car down the ramp. This is the same car that she couldn’t get to stay on the ramp just minutes earlier. I listen as Hudson turns the car over and explains, “See those wheels? The front ones […]
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 […]
Today’s dark skies and heavy rain have driven us indoors for what started out as a low-energy day. But now it’s even quieter—as in “too quiet.” I can feel my anxiety rising. But as I look around and see the children engaged in deep, calm block play—with wooden blocks strewn all over our classroom—I break […]
As I look around me, I see busy, contented children. Jimmy and Tali are seeing how high they can stack their rocks. Eve and Noa are creating a tea party for fairies near the sandbox. Eleanor and Salli are creating homes and meals for the squirrels who frequent the rain garden. Everyone is happy and […]
Each spring, we eagerly anticipate the arrival of the growing season—from the greening carpet of grass to the buds bursting into blossom on the trees. We especially delight in the dandelions that can turn any grassy area into a STEM wonderland! Dandelions introduce so many math adventures into our early childhood program. The neighborhood park […]
“I smell cinnamon rolls!” exclaims Henry as he races through the gate towards our outdoor classroom. Everyone stops what they are doing to inhale deeply. “I do too! I want a cinnamon roll!” pleads Noah. My group is quite disappointed to learn that I am not baking cinnamon rolls this morning. The delicious cinnamon-roll […]
“Hey everybody! Look at all of the tomatoes that are ripe today!” shouts Jacob to the gang. “Can we eat them for lunch? Can we?” asks Lucus. “Can we eat them now?” pleads Elizabeth. It’s early September and preschoolers around the country are learning about apples, but we have tomatoes at our fingertips. The same […]
As the days grow shorter and the slanting rays of sun that create our rainbows are replaced by clouds, we shift our energy to other forms of investigative play with light and color. “Saaliha, come play with me at the light table!” Nora calls out. Saaliha joins her friend and the STEM investigations into […]
“LOOK! We have icicles!” “Can I have one? I need one!” On this brisk winter morning—much to the children’s delight—nature has given us the gift of icicles. The children’s fascination with these frozen treasures leads to an abundance of “teachable moments” as we engage in some STEM learning while getting some fresh air and exercise. Soon […]
“Can you read it again? PLEASE?” Frigid temps and gray days lead to lots of reading as we weather the winter season. As February unfolds, I am thrilled to present a series of STEM books guaranteed to educate, enrich and entertain early learners while the snow flies. It’s difficult to find books that balance exceptional […]
“Five green and speckled frogs…sat on a speckled log…eating some delicious bugs. Yum yum! I hear a chorus of young voices singing in our outdoor classroom as three young friends hold hands and frolic around in a circle. When we sing counting songs such as “Five Green and Speckled Frogs” or “This Old Man,” […]
Whether you grew up with Schoolhouse Rock, Sesame Street, the Electric Company, Romper Room or Raffi, chances are good that you can still sing a counting song that you learned way back then. Ah, there are some really great songs from those days and many a Schoolhouse Rock version is being used to teach “skip counting” […]

“Fingers, fingers, 1-2-3…how many fingers do you see?” We are playing one of our favorite finger games. I hide one hand behind my back. When I bring it forward, I hold up some fingers and the children shout out the number of fingers that they see. “Three!” shout the friends playing the game. […]
“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 […]
