Sharing and Dividing Fairly

Dividing Things Up

When you share things with friends or family, you use math to make sure everyone gets the same amount.

Why Sharing Matters

Fair sharing helps everyone feel happy and included.

Math in Everyday Sharing

You can use counting and simple division to split things like snacks or toys.

Examples

  • Splitting 8 cookies evenly among 4 friends so each gets 2.

  • Dividing 12 crayons between you and your friend.
