Montessori sensorial materials are materials used in the Montessori classroom to help a child develop and refine his or her five senses. Use of these materials constitutes the next level of difficulty after those of practical life.
Like many other materials in the Montessori classroom, sensorial materials have what is called "control of error", meaning that the child not only works with the material, but has a way to check their work rather than seeking out the teacher if they have a question on whether or not they did it right. This is done to help promote independence and problem solving on the part of the child.

Cylinder blocks
Small, tall and short, thick and thin, and combinations of these.
The cylinder blocks are ten wooden cylinders of various dimensions that can be removed from a fitted container block using a knobbed handle. To remove the cylinders, the child tends to naturally use the same three-finger grip used to hold pencils.
Several activities can be done with the cylinder blocks. The main activity involves removing the cylinders from the block and replacing them again in the spot that one got them from. The control of error is constituted in the child's inability to replace a cylinder in the wrong hole.
Pink tower
The pink tower has ten pink cubes of different sizes, from 1 centimeter up to 10 cm in increments of 1 cm. The work is designed to provide the child with a concept of "big" and "small."
The child starts with the largest cube and puts the second-largest cube on top of it. This continues until all ten cubes are stacked on top of each other.
The control of error is visual. The child sees the cubes are in the wrong order and knows that they should fix them. The successive dimensions of each cube are such that if the cubes are stacked flush with a corner, the smallest cube may be fit squarely on the ledge of each level
Broad stair
The broad stair (also called Brown Stair) is designed to teach the concepts of "thick" and "thin". It comprises ten sets of wooden prisms with a natural or brown stain finish. Each stair is 20 cm in length and varies in thickness from 1 to 10 cm. When put together from thickest to thinnest, they make an even staircase.
As an extension, the broad stairs are often used with the pink tower to allow the child to make many designs.
Red rods
The red rods are rods with a square cross section, varying only in length. The smallest is 10 cm long and the largest is one meter long. Each rod is 2.5 cm/1inch square. By holding the ends of the rods with two hands, the material is designed to give the child a sense of long and short.
Colored cylinders
Also called the knobless cylinders, the colored cylinders are exactly the same dimensions as the cylinder blocks mentioned above.
There are 4 boxes of cylinders:
- Yellow cylinders that vary in height and width. The shortest cylinder is the thinnest and the tallest cylinder is the thickest.
- Red cylinders that are the same height, but vary in width.
- Blue cylinders that have the same width, but vary in height.
- Green cylinders that vary in height and width. The shortest cylinder is the thickest and the tallest cylinder is the thinnest.
The child can do a variety of exercises with these materials, including matching them with the cylinder blocks, stacking them on top of each other to form a tower, and arranging them in size or different patterns. When the yellow, red, and green cylinders are placed on top of each other, they all are the same height.
Binomial cube
The binomial cube is a cube that has the following pieces: one red cube, three black and red prisms, three black and blue prisms, and one blue cube.
A box with eight prisms represent the elements of or:
The pieces are stored in a box with two hinged opening sides. The color pattern of the cube is painted all around the outside of the box (except the bottom).
The material is not designed as for math education until the elementary years of Montessori education. In the primary levels (ages 3-6), it is used as sensorial material.
Trinomial cube
The trinomial cube is similar to the binomial cube, but has the following pieces instead:
- 1 red cube and 6 black and red prisms (varying in size)
- 1 blue cube and 6 black and blue prisms (varying in size)
- 1 yellow cube and 6 black and yellow prisms (varying in size)
- 6 black prisms (same size)
This is similar to the binomial cube, but is a physical representation of this formula:
