In this unit pupils will use knowledge of 1000 to explain common measure conversions and solve problems.

Lesson Summary

You will learn to partition 1,000 and 2,000 in the context of measures.

Key Notes

  • There are 1,000 m in a km
  • There are 1,000 mm in a m
  • Convert between km and m to simplify a problem.
  • Convert between m and mm to simplify a problem.

Vocabulary To Learn

  • Scale: Scale is the value of the divisions marked on measuring equipment or the axes of a graph.

  • Pupils may not see the link between partitioning 100 into 2, 4, 5 and 10 equal parts and partitioning 1,000 into those equal parts.

3 Quick Questions (With Answers)

1. Solve this in steps: explain the method from this lesson and why each step matters.

There are 1,000 m in a km. There are 1,000 mm in a m.

2. Use this key word in a maths sentence and explain it clearly. 'Scale'

Scale is the value of the divisions marked on measuring equipment or the axes of a graph. Use this word when showing your method, then check your final answer is reasonable.

3. Spot and fix this common maths mistake.

Mistake: Pupils may not see the link between partitioning 100 into 2, 4, 5 and 10 equal parts and partitioning 1,000 into those equal parts. Correction: You may wish to revisit partitioning 100 into equal parts, using representations familiar to pupils, to help them to understand that their knowledge of partitioning 100 can be applied to partitioning 1,000.
