About this skill
Estimation and benchmarks help: a door is measured in metres, a coin's thickness in millimetres.
How to teach it
- Measure real objects around the house.
- Estimate before measuring, then check.
- Know benchmarks: a finger is about 1 cm wide, a door about 2 m tall.
Mistakes to watch for
- Starting the measurement at 1 instead of 0.
- Choosing silly units, such as kilometres for a pencil.
