What are number bonds to 10?

Number bonds are pairs of numbers that add together. When we make 10, we find two numbers. They join together to make 10. This is really useful!

Finding partners for 10

Every number from 0 to 10 has a partner. The two partners always add up to 10. If you know one number, you can find its partner.

Why number bonds help us

Knowing pairs that make 10 helps you add quickly. It helps you take away too. You can use them every day!

Using your fingers

Hold up some fingers on one hand. Count them. Now hold up more fingers to make 10 altogether. You made a number bond to 10!
