The Broad (Brown) Stairs consist of ten hardwood prisms ranging from 1 cm x 1 cm x 20 cm to 10 cm x 10 cm x 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.
Color may not be exactly as shown.
Recommended ages: 3 years and up.
