“Did you get new blocks?” four-year-old Marlo shouts as she makes a beeline for a table piled high with SumBlox, our newest early math learning tool.

Without waiting for an answer, she begins stacking the blocks into a tower. Suddenly she stops and asks: “Hey! Are these numbers?” 

“Yep, they are number blocks,” I confirm. “There are lots of different ways to play with them.”

Marlo tilts her head, looks at me quizzically for a second, and then begins to arrange the blocks in numerical order. Within minutes, she has another epiphany.

“Every number gets bigger and taller!” she notes with excitement.

Five-year-old Seana joins Marlo at the table.  “These are cool!” she exclaims.

I continue to observe as these two early learners explore our newest playful math tools.

Just when I thought wooden blocks couldn’t get any better, I discovered SumBlox: wooden blocks shaped like the numbers 1 through 10.

But here’s what truly unique about this block set: Each block’s size reflects its numerical value. For example, the #2 block is twice as tall as the #1 block and the #10 block is 10 times as tall as the #1 block.

These simple yet powerful blocks help children spot numerical patterns and understand the relationships between numbers.

It isn’t long before Seana figures out the magic of these blocks.

“When I stack two blocks together to make them add up to 10 and then line up the different stacks, they are all the same height!” she reports.  (See image above.)

Wow! I think to myself. I love how those little brains work!

Seana smiles and I can see her confidence grow as she stacks different sets of numbers. Her number sense is growing as she “plays” with different number block combinations.

Because the blocks are different heights based on the numbers that they represent, they give children a fun, hands-on way to see how numbers work together, like finding different “friends” for each number that add up to the same amount.

As Marlo and Seana continue to play with the SumBlox, they are learning that different combinations of numbers can form the same total—a key early math concept.

When children can physically manipulate number blocks, they can better understand the concept of  “how much” each number represents. For example, when children see that the #3 block is three times taller than the #1 block, they begin to understand that 3 is more than 1—and the size difference helps them see how numbers grow.

This hands-on approach is especially helpful for visual learners who grasp concepts better by seeing and doing rather than by listening to someone explain the concepts. As children arrange the blocks in various combinations, they can start to recognize patterns such as how numbers add up or how removing some blocks makes a smaller number.

Because the blocks are proportional in size to the numbers they represent, children can see how numbers combine in a visual way.

By placing the #4 and #5 blocks next to the #9 block (see image above), children can see that the heights match, which helps them grasp the idea that 4 + 5 is the same as 9.

Children can also explore how to break down the number 10 into different parts, such as 5 + 5 or 6 + 4, and even experiment with more complex combinations such as 5 + 2 + 3 to reach 10.

This “seeing and touching” approach enables young learners to connect with numbers in a deeper, more meaningful way.

Instead of simply knowing what a number looks like, children begin to understand what that number really represents—how numbers relate to each other, how they change, and how they can be combined or broken down.

All of this helps children develop number sense—a key early math skill.

Number sense can be challenging for young learners to grasp because it involves abstract concepts such as quantity and number relationships.

SumBlox makes these concepts a bit less “abstract” by giving children a hands-on opportunity to practice ordering numbers, which helps them gain confidence as they make and correct mistakes.

As the numbers increase in value, the blocks get taller too, offering a visual cue to help kids understand the concepts of “more” and “less.”

This hands-on approach also makes it easier for children to see the relationships between numbers. As they stack and arrange the blocks, they can practice number recognition, counting, addition, and subtraction. Our more advanced and intrepid early math learners can also explore basic multiplication, division, and fractions.

I love how these blocks also help children spot patterns in numbers and understand how numbers relate to each other.

By observing how towers composed of various SumBlox are taller or shorter, children can see how numbers grow in predictable ways. Simple activities such as putting the blocks in order from 1 to 10 help build number recognition skills, while fostering an understanding of the value represented by each number. Children can begin to see that 10 is much bigger than 1, not just by recognizing the number, but by seeing the difference in the size of the blocks.

A SumBlox set offers a powerful, hands-on way for young learners to explore and understand key early math concepts. Through play, children can physically see and feel the relationships between numbers, which helps build a solid foundation for more advanced math learning down the road.

Playful learning truly makes math enjoyable and meaningful for young minds.

“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!
