Lesson details

Key learning points

  1. If you can halve a multiple of 4 then it is a multiple of 8 and divisible by 8
  2. All numbers divisible by 8 are also divisible by 4 and 2
  3. Multiples of 8 are all multiples of both 2 and 4

Common misconception

Lack of fluency in 4s and or 8s times tables and understanding when tackling word problems.

Clearly model highlighting key words of worded problems to understand the problem and the operation required for the calculation. Continue to use language stems such as 'If I know...' 'Then I know...,' to support mathematical thinking.

Keywords

  • Halve - A half is one of two equal parts of a whole.
