Explain the relationship between adjacent multiples of eight

I can explain the relationship between adjacent multiples of eight.

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

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.

Keywords

  • Adjacent - Adjacent means next to each other.

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

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.
