Measurement Lab
Measure it up!
Switch between cm, m, g, kg and litres. Start Easy with whole-number swaps — then level up!
Next: pick Easy, Medium or Hard!
Tap a level to start - you can always try again!
Warm-up - you have got this!
Ready for a challenge!
Super hard - go for it!
Compare lengths, masses and capacities and choose sensible metric units. Builds estimation before formal conversion work.
Pick a level, read the measurement scenario, and choose the best unit or comparison.
Ask “would I use cm or km for this?” before looking at the numbers.
Builders, nurses, chefs and athletes measure constantly. Choosing a sensible unit is half the skill of getting an accurate answer.
Measurement links maths to PE, cooking and science experiments.
Ages 7–12.
Mixing m and km — remind them kilo means thousand.
