The sensorial materials in a Montessori classroom are colorful, attractive to children and designed to educate and refine the senses. Each material focuses on an increasingly complex attribute. The pink cubes increase in volume. The brown prisms increase diameter while the red rods increase in length. There are materials designed to bring out the child’s awareness of touch, smell, color, and geometric shapes.
Work with the Montessori sensorial materials has indirect benefits that are not easily seen. Many of the materials are designed with ten elements and are based on the properties of the metric system of measurement. Children discover relationships among the materials and can use them as a unit of measurement. Hand strength, eye hand coordination, and work with patterns are all skills that support the development of reading and writing.
