Develop visual discrimination of length with the Long Red Rods and base, an essential Montessori sensorial material designed for CASA classrooms.
Product Description
The Long Red Rods with Base is a foundational Montessori Sensorial material designed to introduce children to the concepts of length, measurement, and comparison. This set includes 10 red wooden rods ranging from 10 cm to 100 cm in consistent 10 cm increments. Each rod has a cross-section of 2.5 cm², allowing children to visually and physically compare differences in length. The set includes a sturdy wooden base for organized storage and display, supporting a prepared environment in both Montessori classrooms and home settings.

How to Use
Present the rods by arranging them in a stair-like sequence from shortest to longest on a working mat. Encourage the child to explore by comparing, ordering, and measuring visually and by touch. As children repeat the activity, they internalize concepts of size, order, and incremental difference—key elements in early math education.
