Lesson details

Key learning points

  1. Multiplication can be used to represent equal groups.
  2. The x symbol represents times.
  3. One number in the multiplication represents the number of groups and the other the number in each group.

Common misconception

Children are not able to explain the multiplication expression.

Children are encouraged to identify exactly how the equation relates to the image. For example 3 groups of 2 shoes: 3 x 2 - with the questions ‘What does the 3 represent?’ ‘What does the 2 represent?’ ‘What does the 6 represent?’

Keywords

  • Groups / grouping - A set of things with an identity.

  • Multiplication - The basic idea of multiplication is repeated addition, adding a number to itself multiple times. The result of a multiplication is a product.
