Lesson

When we write a number, each digit stands for a different value. When we partition a number, we break it up into these different parts. Can you see the word 'part' in partition? By breaking a number into parts, we can do things like share the number, by sharing each part separately.

Have a look at this video to see some different ways to break up a number, as well as an example showing you how you might use these new parts of your number.
