Choosing measurement units
PROCEDURALChoose and use appropriate standard units to measure length (m/cm), mass (kg/g), temperature (°C), and capacity (litres/ml) to the nearest appropriate unit
Mastery Evidence
- Measure the length of a table in centimetres using a ruler
- Weigh an object in grams using a scale
- Measure the capacity of a container in millilitres using a measuring jug
Assessment Prompt
“If you ask [child] whether to measure a swimming pool or a piece of paper in cm or m, can they pick the sensible unit for each — and explain why?”
Curriculum Standards1 alignment
Maths/Y2/M/1The national curriculum in EnglandChoose and use appropriate standard units to estimate and measure length/height in any direction (m/cm); mass (kg/g); temperature (°C); capacity (litres/ml) to the nearest appropriate unit, using rulers, scales, thermometers and measuring vessels.

- Capacity and volume hard
Using standard units for capacity extends from beginning to measure capacity
- Comparing Capacity hard
Measuring capacity with units requires first being able to compare capacities
- Measurable Attributes of Objects hard
Comparing capacity requires understanding capacity as a measurable attribute

Using standard units for length extends from beginning to measure length
- Comparing Lengths & Heights hard
Measuring length with units requires first being able to compare lengths directly
- Measurable Attributes of Objects hard
Comparing lengths/heights requires first identifying length as a measurable attribute
- Measuring mass and weight (age 4+) hard
Measuring mass with units requires first being able to compare masses directly
- Measurable Attributes of Objects hard
Comparing mass/weight requires first identifying mass as a measurable attribute
