Lesson details

Key learning points

  1. Repeated addition can be written as a multiplication.
  2. The x symbol represents times.
  3. 3 groups of 5 can be represented as 5 + 5 + 5 or as 3 x 5
  4. 3 represents the number of groups and 5 represents the number in each group.

Common misconception

Pupils may not understand how to represent the repeated addition expression and a multiplication expression.

Encourage pupils to identify exactly how the equation relates to the image: with the questions ‘What does the 3 represent?’ ‘What does the 2 represent?’ ‘What does the 6 represent?’

Keywords
