What are number bonds?

We’re hunting down some number bonds.

Number bonds are a pair of numbers that add up to another specific number.

Let's try tracking down as many number bonds as we can for the number 10.

There you go! 6 and 4.

Once added together they create the number 10!

As do 5 and 5.

Now let's have a go at finding some of the number bonds for the number 20.

10 and 10 work!

And 12 and 8. And many more.

The higher the number the more number bonds it will have.
