10 more and less

This week the children have been learning to find 10 more and 10 less.

We started by using a 100 square to find the pattern - what happens when you add 10 or find 10 more?  (Looking at how the units stay the same and the tens side has one more ten)

The children set off on their own with a whiteboard and had a go by themselves.
i.e.

10 more than 25 is ____

10 more than 54 is _____

or

24 + 10 = ______

16 + 10 = _______

(We discussed how 10 more and + 10 are the same thing)


In the same way we explored 10 less and - 10.
