Measure Lab
Measurements pair a number with a unit; instrument marks show equal intervals, and converting units changes the number without changing the amount.
What your child will figure out
- Read length from evenly spaced centimetre and inch marks.
- Read mass and capacity scales in grams, kilograms, millilitres, and litres.
- Convert between related metric units while preserving the measured amount.
- Build fluency across a twelve-mission campaign, then solve procedurally generated measurements as precision and unit complexity adapt to performance.
The levels
- Laser ruler
Predict, set, observe, and explain a centimetre reading from equal ruler intervals.
- Gravity balance
Read a mass pointer by finding the value of each tick on a gram scale.
- Bubble jug
Read a liquid level from a millilitre scale and explain how tick values are determined.
- Unit portal
Transfer measurement reasoning by converting the same amount into a novel unit without changing it.
- Moon shard
Read a length that ends on a half-centimetre interval.
- Comet dust
Infer and use 50 gram intervals on a denser mass scale.
- Star serum
Read capacity accurately from 50 millilitre intervals.
- Distance beam
Convert centimetres to metres while preserving length.
- Micro-meteor
Read an imperial ruler at quarter-inch precision.
- Gravity gel
Read a decimal mass directly in kilograms.
- Nebula vial
Reverse the familiar capacity conversion from litres to millilitres.
- Asteroid certificate
Transfer measurement reasoning by converting a fine gram reading into decimal kilograms.
