Explain how many '500s' and '250s', 1,000 is composed of
Lesson details
Learning outcome
I can explain how many 500s and 250s 1,000 is composed of.
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.
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.
Division - Equal divisions refer to equal spacing on a number line or scale.
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.
Teacher tip
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.
