Learning About Volume

Geometric solids and volume materials help children feel the difference between a cube, a cylinder and a sphere before naming them. Lifting, stacking and comparing pieces builds an intuitive sense of size and weight, the foundation for later work on 3D shapes.

• Wooden 3D geometric solids with a drawstring bag for guessing shapes by touch.
• Montessori cylinder blocks with four bases to compare volume and weight.
• The pink tower with 10 visual cards and a giant rainbow stacker to grade sizes.
• A blue balance scale with four brass weights, and a geometric fraction blocks and solids set.
• A 12-compartment sorting tray for heuristic play and sorting by shape.
