Weight and Comparative Rate, 21 pcs., in a cardboard box

By weighing and comparing using these filled plastic cubes (feathers, wool, gravel, iron, aluminium, etc.) pupils can easily learn about sizes and weight as well as their connectionwith one another. The relationships between "heavier", "lighter" and "equal weight" can be visualised.

The weight comparison set conveys real concepts at different weights and encourages familiarity. The set contains 10 filled plastic cubes and 9 additional cubes which can be filled yourself. Also comes with 2 measuring beakers for easily filling the cubes. By comparing different materials and confirming this using the scales, estimates can be checked and weights identified.
