Estimating Lengths
Estimate lengths using units of inches, feet, centimetres, and metres
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
- Estimate the length of a classroom object before measuring it
- Use a known reference (e.g. width of a finger ≈ 1 cm) to make reasonable estimates
- Check estimates by measuring and evaluate how close they were
Assessment prompt
If Estimating Lengths looks at a car parked outside, can they estimate roughly how many metres long it is — and then check whether their guess was reasonable?
