Key learning points

There are ___ groups of ___
The groups can be represented with an addition.
There are ___ and ___ and ___
There are ___ + ___ + ___

Common misconception

Pupils might confuse the number of groups with the value of the groups and therefore write incorrect expressions.

Once familiar with building the relevant additive expression, the multiplicative expression is introduced alongside e.g. 3 + 3 + 3 + 3 + 3 is the same as 5 x 3 Take time to connect these ideas using `groups of language' and physical representations.
