Box with Prisms for the Brown Stair

Description

The Box with Prisms for the Brown Stair contains 10 wooden prisms. The child uses these to calculate the volume (area) of the prisms of The Brown Stair. The prisms are all identical in length and breadth, but the thickness of each prism differs. Prisms introduce the concept of comparatives of thickness or thinness and area and volume.

10 solid beechwood prisms

Wooden Montessori Materials - Features and Care Instructions

One of the attractions to the Montessori Method is the extensive use of wood.

We use several types of wood, sourced from renewable sources, in the production of our Montessori Materials.

Solid beechwood for cylinder blocks, pink towers, dressing frames and brown stairs.
Birchply for trays, holders and animal and botany puzzles.
MDF for puzzle maps
Pineply for boxes and containers

We ensure that the coatings and inks used are not only eco-friendly, but also non-toxic.

Our wooden products are manufactured by responsible partner factories both locally and abroad and ensure that fair labour practices are adopted.

Care instructions for Childrens House Wooden Materials:

If wooden products are exposed to liquids, wipe dry as quickly as possible.
Most of the surfaces can be wiped with a damp cloth if exposed to dirt or grime.
Avoid leaving any of our wooden product in direct sunlight, as it may warp certain woods and/ or the coating may fade over time.
