### Common misconception

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

Spend time developing confidence in counting in multiples of 100 and 200 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 parts that make up the whole.

Counting in Multiples - When we count by a number other than 1

Divisions - Equal divisions can be found on a number line or scale for equal values.

Estimation - We find a value that is close enough to the right answer, usually with some thought or calculation involved.
