Let’s ReviewExtension Activities3 Number Bingo

The students gather a piece of paper, a pencil and 3 die. Every student draws a 3 by 2 grid on their paper.1

2 Choose 6 decimal numbers ranging from 20 to 30, only in the tenths place. The leader rolls the 3 die.

3 The pupils use the 3 numbers generated to try to make any of the numbers on their grid using any operation.

4 If successful the number should be crossed out and the mathematical statement used should be written under the grid. The first student to complete their grid is the winner.

Let’s ReviewExtension ActivitiesVocabulary Chains

Children work in pairs. The leader starts thegame giving the class a starting word, for example ‘decimal’. Then pairs use the wordin turns to think of other mathematical vocabulary that are related. Pairs record their chain and share it with the class.
