This Broad (Brown) Stairs consist of five hardwood prisms ranging from 2 cm x 2 cm x 20 cm to 10 cm x 10 cm x 20 cm. Width and increases in increments of 2 cm, while length remains fixed at 20 cm.
This series of prisms demonstrates to the child the change in width (breadth) while the length of 20 cm remains constant. Further practice with the Broad Stairs indirectly prepares the child for concepts in plane geometry, area and volume.
Made exclusively for toddlers.
