Product Description

The Brown Stair consists of 10 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 breadth (width) , while the length of 20 cm remains constant. In fact, the practice of using brown stairs is to prepare children to prepare the concept of plane geometry, area and volume.
