Weigh the catch on a balance scale: add kilo-weights until the beam sits level to find a mass, or make one pan heavier or lighter.
Loading weights onto a pan until the beam sits level reveals an object's mass — or the task shifts to making one side clearly heavier or lighter than the other. The rounds develop understanding of weight, mass, and measurement with standard units, alongside the ability to compare quantities on either side of a scale. A natural fit for Grades 2–4, or any child beginning to explore measurement with physical tools.
A free, no-signup, no-ads math game for Grades 2–4 — practising weight, mass, measurement, comparing-numbers. Play in your browser on the KidsDoMath games hub or explore more Measurement games.
