Brown Stair

This set includes 10 brown, beautifully polished cuboids that demonstrate changes in width and height, while the length remains constant at 20 cm. The rectangular prisms vary in area from 1 square centimeter to 10 square centimeters. The cuboids are precisely cut to ensure accuracy and help children develop a visual and muscular understanding of dimensions.

This material is one of the first in the Montessori sensorial journey, following the Cylinder Blocks and Pink Tower. It aids in understanding basic mathematical concepts related to numbers 1-10, providing a foundation for more advanced mathematical materials in the Montessori environment.
