Free Y4 maths worksheets: Relate addition and subtraction

calculate 2One of the most important concepts for children to understand in the early years is the relationship between addition and subtraction. Given one set of facts they should be able to deduce several other facts.

For example:

If 40 + 30 = 70 then:

30 + 40 = 70

and

70 – 40 = 30

and

70 – 30 = 40.

These two free worksheets look at this relationship.
