Measure in standard units (m, cm, kg, g, l, ml)
Choose and use appropriate standard units to estimate and measure length/height (m/cm), mass (kg/g), temperature (C) and capacity (litres/ml)
What you'll learn
- 1
Standard units are the ones everybody agrees on: cm and m for length, g and kg for mass, ml and l for capacity.
- 2
If you measured a room in footsteps, your answer and a grown-up's would be different — because your feet are different sizes.
- 3
Which unit would you use to measure a pencil?
- 4
Pick the unit to match the size. Big things get big units, small things get small units.
- 5
To measure the school hall you use metres, not centimetres. 20 m is far easier to say and picture than 2000 cm.
- 6
Which unit for the mass of a bag of flour?
- 7
Why do we use standard units instead of footsteps?
