Ten graduated prisms guide children toward independently distinguishing width and thickness. While building the stair, they gain an intuitive understanding of relationships between sizes.
The material contains hardwood prisms, all with the same length of 20 cm. Their dimensions gradually change from 1 × 1 cm to 10 × 10 cm.
Arranging the prisms in the correct sequence develops logical thinking, a sense of order and provides a foundation for later work with mathematical concepts.
The Montessori Brown Stair consists of ten hardwood prisms, each 20 cm long. The individual pieces gradually differ in width and height, from the smallest prism measuring 1 × 1 × 20 cm to the largest measuring 10 × 10 × 20 cm. The child arranges them from widest to narrowest to create the characteristic stair, while the correct arrangement can easily be checked visually and by placing the prisms against one another.
Working with the material supports concentration, order, precision of movement and independent discovery. Through handling the prisms, children naturally learn the concepts of narrow, wide, thin, thick and their gradations. The material is also suitable for expanding vocabulary and for a first introduction to the principles of the decimal system.
