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 1x1x20 cm to 10x10x20 cm.
