Number Bonds to 10
Kindergarten · Math · Study Guide
Learn how two numbers can join together to make 10.
A number bond shows how two numbers add together to make a bigger number. When we talk about number bonds to 10, we are looking for pairs of numbers that add up to 10.
Think of a number bond like a family. The big number 10 is the parent, and the two smaller numbers are the children. For example, 6 and 4 are a number bond pair because 6 + 4 = 10.
Here are all the number bond pairs for 10: 0 and 10, 1 and 9, 2 and 8, 3 and 7, 4 and 6, 5 and 5, 6 and 4, 7 and 3, 8 and 2, 9 and 1, and 10 and 0.
You can use your fingers to help! Hold up all 10 fingers. If 3 fingers are down, how many are up? That gives you the number bond pair: 3 and 7.
Knowing number bonds to 10 helps you add and subtract numbers really fast. It is one of the most important math skills you will learn in kindergarten!
