Montessori Red Rods with Stand

What are the Red Rods?
The Red Rods are part of the Montessori Sensorial Curriculum.
It is common for sensorial materials to isolate one quality, such as weight, to assist the child in better understanding their environment.
 
The Red Rods are comprised of 10 wooden rods, differing in one dimension, length. The smallest rod is 10cm long, and the largest rod is 100cm. Each rod increases by increments of 10cm in length.
 
Purpose:
The Red Rods are introduced to children from 2.5 to 6 years of age. This is often after they have worked on preliminary sensorial materials, such as the Knobbed Cylinders, Pink Tower, and Brown Stairs.
 
The direct purpose of the Red Rods is to develop the child’s visual and muscular perception of length.
 
Secondary aims include: developing the child’s coordination of movement, assisting with balance and concentration, and providing the child with the basic language of mathematics.
 
Through repetition with the Red Rods, the child will learn to discriminate between long and short, build the rods in a stair formation, and find disharmony in building the rods incorrectly.
