Numeracy WB 17.05.10

In numeracy this week we shall be using numberlines and number squares to add and to take away from larger numbers up to 100. It would be helpful if you could practise adding and taking away 10 from any given number. Help them to see that by adding 10 you are effectively changing the tens digit of the number and keeping the units the same.

If they understand this they can move on to add in 11 (by adding 10 and then one more) and adding 9 ( by adding ten and taking one away):

There are some number games on the "Number Square Games" link that are useful for this or click on the links below.
