This series of prisms demonstrates to the child the change in width (breadth), while the length remains constant. Practice with the Brown Stair indirectly prepares the child for concepts in plane geometry, area and volume. The prisms are crafted in precise progressions from 1 x 1 x 20 cm to 10 x 10 x 20 cm.
