Key learning points

There are two 500s in 1,000
There are four 250s in 1,000
Knowing how many 500s and 250s 1,000 is composed of helps to interpret scales and measures.

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.
