Metal Volume Containers

The Metal Volume Containers set is a hands-on Montessori material designed to introduce children to the concept of volume, capacity, and the relationships between different geometric solids. The set includes three hollow metal containers shaped as a cube, cuboid, and cone, all painted in Montessori blue. These shapes can hold sand or water, allowing children to experiment practically and discover how volumes compare, measure, and relate to one another.

Through repeated pouring and measuring, children develop a concrete understanding of volume equivalence, ratios, and the mathematical properties of 3D shapes. The material encourages scientific thinking, observation, prediction, and exploration—making abstract volume concepts accessible and engaging for elementary learners. Ideal for classroom demonstrations, small-group lessons, and hands-on discovery work.
