The brown stair – Nienhuis Montessori
The Nienhuis Montessori brown stair with clear lacquer represents a series of solid wooden prisms and demonstrates to the child the change in width (breadth), while the length remains constant.
Working with the brown stair indirectly prepares the child for concepts in plane geometry, area and volume. The series of prisms are part of the Montessori sensorial curriculum and is crafted in precise progressions from 1 x 1 x 20 cm to 10 x 10 x 20 cm.
This material is suitable for children aged 3 years and up.
