Sort into
- even
- odd

An even number divides exactly by two - look at the ones digit: 0, 2, 4, 6 or 8 means even.
02
Sort these numbers into groups.
Sort into
- even
- odd
- 134
- 251
- 308
- 479

Game teaching guide

What children will practise

Tell odd from even for numbers into the hundreds by looking at the ones digit, know that 0 is even, and decide whether products are odd or even.

What's in the worksheet

4 sorting questions, all odd or even - 12, 20 even; 7, 15 odd - 134, 308 even; 251, 479 odd - 0, 66 even; 1, 99 odd - 3 × 4, 2 × 9 even; 3 × 5, 7 × 7 odd

How to use it in class

Use as early-P3 review, about 5 minutes, solo mode; the questions get harder in order. - For 0, discuss before revealing why it is even: 0 splits into two equal piles (that reason is enough at P3) - For products, work out each one first, then notice the rule that odd times odd is odd - Play it linked to the class to record results in the mark book

Common sticking points

- Putting 0 under odd, or being unsure, because 0 does not feel like a number - Calling 251 and 479 even from the 2 or 4 in the hundreds. Cover the hundreds and tens and look only at the ones - Putting 3 × 4 under odd because of the 3. Work out 12 first
