Lesson details

Key learning points

  1. Adjacent multiples of 8 have a difference of 8
  2. If you add 8 to a multiple of 8 I get the next multiple of 8
  3. If you subtract 8 from a multiple of 8 you get the previous multiple of 8

Keywords

  • Adjacent - Adjacent means next to each other.

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

Common misconception

Pupils may not understand the key term 'adjacent,' and have difficult understanding the word problems.

Model correct usage in a range of contexts including labelling abstract equations and using the terms to identify the known elements in worded problems.

The focus of this lesson is using knowledge of multiples of eight, and connecting this to adjacent multiples. Chorally rehearsing the 8 times tables at any given opportunity and playing games to support fluency.
