How to Teach “How Many” to Young Children:
A Fun Way to Build Number Sense
How many are in the box?
Numbers are not just about saying 1-2-3-4-5.
Simply reciting them doesn’t help children truly understand what numbers mean.
What we really want is for children to know how many, to form a mental picture of numbers in their head. This is the foundation for later math skills like addition, subtraction, and problem-solving.
A simple, hands-on activity can make this concept clear and fun for young learners—and it only takes a few toys and a box.
Start with an empty box Use a small box, basket, or pot with a lid. Gather five toys that fit inside.
Ask, “How many are in the box?”
Look together and decide there are zero. Say out loud: “There are zero toys in the box.”
Add one toy at a time:
Ask: “How many toys will there be when this one goes in?” One. Put the toy in the box. “Let’s look and see”. Open the box. Check it. Yes, one toy in the box. Close the box. Pick up another toy. “How many toys will there be in the box when I put this toy in? In it goes!” Check together.
Vary the task
You can add one toy at a time or two toys at a time. Sometimes the toys can get out of the box.
Tip: Make it fun, make it silly, make it giddy. Tip: Always pretend you’re checking because you’re unsure — this makes it fun and reinforces the concept of counting and verifying.
By making counting hands-on, silly and engaging, your child develops a strong number sense that lays the foundation for all future math learning.
