This week we have been looking at 1 more, 1 less, 10 more and 10 less of any given number to 100. The children have been looking at counting in 10’s from any given number. For example 2,12,22,32,42,52. We have looked at patterns with number- what changes in a number if you add 10? We have also counted stacks of 10cent and 1 cent coins to find the total.

For example- 5 x 10 cents = 50

3 x 1 cents = 3 cents

Makes 53 in total

This is a good support tool in explaining this
