Pupils should practice additive calculation within 10 until they have automatic recall of the additive facts.
The 66 addition facts within 10 are shown on the grid below. The number of addition facts to be learnt is reduced when commutativity is applied and pupils recognise that
3 + 2, for example, is the same as 2 + 3.
Pupils must also have automatic recall of the corresponding subtraction facts, for example 5 – 3 and 5 – 2.
