Counting to 100 in the Best Outdoor Math Activity!

Looking for a fun, hands-on way to teach kids about counting to 100? This outdoor math activity is the perfect solution! Not only is it a fantastic way to build math skills, but it also gets kids outside, exploring, and using nature as their learning tools.

RELATED: Looking for more outdoor activities for kids? I’ve got a great list!

This is what I like to call an onion activity — it has layers upon layers of learning built right in. Here’s what kids get to explore with this outdoor math adventure:

• Counting practice — building confidence and familiarity with numbers up to 100.
• Grouping by tens — understanding the concept of 10 groups of 10.
• Seeing 100 in real life — making the abstract concept of 100 concrete.
• Natural exploration — using outdoor items like rocks, sticks, leaves, and pine cones to represent numbers.
• Connection to Nature — giving kids a reason to engage deeply with the world around them while learning.

And let’s not forget: it’s the perfect sittervising activity (my favorite kind of activity — where you get to sit while they do the learning and exploring). More on that in a minute.

How to Set Up the Outdoor Counting Activity

Materials You’ll Need:

• A large cardboard box or a big sheet of paper
• Marker
• Outdoor items: rocks, sticks, leaves, pine cones — whatever you have access to!

Step 1: Create the Counting Board

On your piece of cardboard, divide it into four sections and label each space with the number 100. This will be the visual reminder of what you’re collecting.

Step 2: Start Collecting in Groups of 10

One hundred is a big number — it’s a lot! To make it manageable and less overwhelming, break it down into ten groups of ten. This chunking method is perfect for little ones to understand the concept of 100.

Encourage your child to find groups of 10 outdoor items. For younger kids, you may want to guide their counting or have them listen to older siblings. This repeated counting practice is crucial for building number sense and memorizing the sequence of numbers.

Step 3: Count the Groups Together

Once they’ve collected their 10 groups of 10, it’s time to count them all together. Depending on your child’s age and skills, you might want to lead the counting or encourage them to try it themselves. The moment you see all 100 objects lined up — it’s powerful.

Step 4: Reflect and Compare

Here’s where the magic happens: take a step back and look at all the groups of 100. Ask questions:

• Are these all 100?
• Which collection looks like it has more?
• How can this small pile and that big pile both have 100?

This opens the door to discussing how size doesn’t determine quantity — a big math concept for little minds!

Learning Through Play: The Benefits of Outdoor Counting

This outdoor counting activity does so much more than just teach numbers. It builds:

• Fine motor skills as kids pick up and group objects.
• Critical thinking as they compare sizes and groupings.
• Problem-solving as they decide what objects to collect and how to organize them.

And, best of all, it’s sittervising gold. Kids are busy collecting, counting, and organizing while you sit back, relax, and watch the learning unfold.

Learning Standards Addressed

If you have a school-age child, here are the Common Core State Standards that this activity addresses:

Kindergarten:

• CCSS.Math.Content.K.CC.A.1: Count to 100 by ones and by tens.
• CCSS.Math.Content.K.CC.B.4.a: Pair each object with one and only one number name in the standard order.
• CCSS.Math.Content.K.CC.B.4.b: Understand that the last number name said tells the number of objects counted, regardless of their arrangement or order.

First Grade:

• CCSS.Math.Content.1.NBT.B.2.a: Understand that 10 can be thought of as a bundle of ten ones — called a “ten.”

Making the Abstract Concrete: Why 100 Matters

For young children, the number 100 is enormous — it’s practically mythical! By turning it into something tangible, something they can see, touch, and manipulate, it becomes real.

Suddenly, 100 isn’t just a number they hear; it’s a collection of rocks, sticks, leaves, and pine cones that they built themselves.

Extensions and Variations

Want to take this even further? Try these variations:

Work Up to 1,000: If 100 feels easy, challenge your child to count to 1,000 in groups of 100.

Add Color: Paint your sticks or leaves before counting for some extra flair.

Try Different Outdoor Settings: Do the activity at the beach with shells, at the park with acorns, or on a hike with pebbles.

Why Outdoor Math Activities Matter

Outdoor math activities like this aren’t just about numbers. They’re about learning through experience, exploring nature, and understanding big concepts in a small, manageable way.

And best of all? It’s done with a bit of sittervising magic — because every parent deserves a moment to sit back while the learning happens
