Lesson details

Key learning points

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

Common misconception

Pupils may not understand the keyword adjacent and have difficult understanding the word problems.

Model correct usage in a range of contexts including labelling abstract equations and using the term to identify the known elements in worded problems. Take time to show adjacent on number lines connecting to addition and subtraction of equal groups.

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 three, and connecting this to adjacent multiples. Chorally rehearsing the 3 times tables at any given opportunity and playing games supports fluency.
