The Brown Stairs: Clear Lacquer

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