Column Subtraction and Addition

We have been doing addition and subtraction this week in Maths.

We have been using counters and a place value grid to show how to subtract with exchanging. We also show how to set out subtraction using column method.









We have also looked at using counters to help us understand why we carry tens across when adding in column addition.
