Measuring with different units
Measure the length of an object using two different length units and describe how the measurements relate to the size of the unit chosen
Suggested ages 7–8
Learning journey
Your child is learning practical measurement skills — using rulers and other tools to measure length, weight, and volume accurately, working with money, and telling time to the nearest minute.
Evidence of understanding
- Measure a desk in both centimetres and inches and compare the two numbers
- Explain that measuring with a smaller unit gives a larger number
- Predict whether a measurement in centimetres will be greater or less than in inches
Assessment prompt
If Measuring with different units measures the same book in centimetres and then in inches, can they explain why the numbers are different even though the book hasn't changed size?
