Day 5

Learning Focus: Equivalent Length mm & cm

This lesson you will be able to recognise that 10 mm is equivalent to 1 cm. You will use  this knowledge to convert other multiples of 10 mm into centimetres and vice versa. When looking at lengths that are not multiples of 10, You can partition the measurement and convert into centimetres and millimetres.

Key Questions: 

  • What items might we measure using millimetres rather than centimetres? 
  • If there are 10 mm in 1 cm, how many mm would there be in 2 cm? 
  • How many millimetres are in 1 2 cm? 
  • How many different ways can you partition 54 cm? 


Once you have worked through the PowerPoint, complete the work in your pack.
