Lesson details

Key learning points

There are ten 100s in 1,000
There are five 200s in 1,000
Knowing how many 100s and 200s 1,000 is composed of helps to interpret scales and measures.
Knowing the composition of 1,000 can help to work out the meaning of each division on scales and number lines.
We can use our knowledge of divisions on a scale to estimate.

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.

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.

Encourage children to use and apply known facts when calculating from scales and graphs rather than referring to counting on. Although not counting on in ones, children have a range of strategies to calculate the sum and difference that will prove more efficient than counting on.
