Game teaching guide

What children will practise

Count on in twos from 2 to 16, order odd numbers smallest-first, and count back in twos from 10, to see the pattern of even and odd numbers.

What's in the worksheet

4 rounds, a put-in-order game with 4 numbers each - Counting on in twos: 2, 4, 6, 8 - Carrying on in twos: 10, 12, 14, 16 - Odd numbers smallest-first: 1, 3, 5, 7 - Even numbers largest-first: 10, 8, 6, 4

How to use it in class

Use once children count in ones to 20 fluently. 5 minutes. - Before playing, count 1 to 16 clapping softly on odd numbers and loudly on even ones - Play as a class; for round 2, count on aloud from where round 1 ended - If many miss round 4, hop back in twos along a number line, skipping one each time - Play it linked to a class and the scores go into the class gradebook.

Common sticking points

- In round 2, children not yet fluent with 12 and 14 may swap them - In round 4, ordering smallest-first because every earlier round was - In round 3, unsure what odd means, so ordering by size without understanding
