## Jigsaw Numbers

If you think of a 2-piece jigsaw with a number on each piece, what do they add up to? Jigsaw Numbers are special (10, 100, or 1000 for example). Explain the jigsaw analogy and ask children to complete the jigsaw, simple! For example, if 4 is one jigsaw piece, ask the child if they can tell us what would be on the missing piece if the total is 10. If we can *see* the maths it helps us to *understand* the maths.

### Jigsaw Numbers to 10

Ready for the challenge of Jigsaw numbers to 10? This is an oral activity to enjoy, have fun with it! Just ask your child to tell you the bottom number (when added to the top number equals 10), then refresh the screen. In this example, the correct answer is 6! How fast can you go?

When you can answer both simple sums quickly, and you want to increase the challenge further, try reframing the questions;

- just ask the subtraction question (100 – 32 = ?) or,
- ask a missing number box questions (32 + = 100), or
- placing the questions into the context of money, or other units of measure (£1 – 32p = ?).

*Each of these questions uses 32 (from the first example provided above).*
