Lesson details

Key learning points

  1. There are two 500s in 1,000

Common misconception

Pupils unable to connect scale divisions with knowledge of composition of 1,000

Spend time developing confidence in counting in multiples of 500 and 250 to 1,000 before making explicit links between this and scales and measures. Use 'The whole is 1,000 and we have divided it into ___ parts of ___' when doing this.

Keywords

  • Compose - The composition of the whole is the way in which it is made.

  • Multiples - The result of multiplying a number by another whole number.
