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.
Construct the stair as before and place the smallest prism on each stair one after the other. This helps the child to observe the difference in dimension that exits between each prism. The difference between any two prism in successiion is always the smallest prism.
