Lesson details

Key learning points

  1. There are ___ groups of ___
  2. The groups can be represented with an addition.
  3. There are ___ and ___ and ___
  4. 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.

Keywords

  • Repeated addition - The process of adding the same equal group to itself multiple times.

In this lesson, children start to describe their equal groups using addition expressions. This is a great opportunity for children to practise writing their own expressions and mathematical symbols.
