Description
The Broad Stair (also called Brown Stair) is made up of ten wooden prisms. While the prisms are all the same length (20 cm), they vary in thickness from 1 to 10 cm. When put together from thickest to thinnest, they make an even staircase.
These are ten hardwood prisms that are painted in brown lacquer. They are graded in width while the length remains constant. These cubes develop visual and muscle perception of dimension. The child will be able to understand different mathematical concepts by using this material.
