Why this why now
This unit gives pupils the opportunity to apply their understanding of decimal place value in the context of measure, converting between metres and centimetres. They will use mental, informal and formal methods to calculate with length and include three decimal places when comparing, ordering and solving problems with length. They will then go on to apply their decimal place value understanding in the context of money.
Prior knowledge requirements
- Understand tenths and hundredths as decimals
- Convert between cm and m
- Compare and add lengths with the same or related units
