Lesson details

Key learning points

  2. Multiples of 8 are double the multiples of 4
  3. Multiples of 4 are half the multiples of 8

Common misconception

Pupils may find it difficult to solve problems or misunderstand questions.

Model clearly how to identify key phrases and words which will identify the operation and equation required for word problems. This could involve drawing bar models or other representations.

Keywords

  • Multiple - A multiple is the result of multiplying a number by another whole number.
