This activity is one of the first sensory activities we introduce to children in the Montessori classroom. The knobbed cylinders are wooden cylinders of varying diameters and heights, all of which must be inserted into the correct holes. The child is asked to insert the correct size cylinder into the correct holes. If the child makes a mistake and places the corkscrew in the wrong hole, the activity cannot be completed and the child must figure out what went wrong and arrange the corkscrews in the correct holes.
What are Montessori Knobbed Cylinders?
Montessori knobbed Cylinders are a piece of Montessori sensory material specifically designed to encourage children to differentiate between sizes and shapes in their immediate environment. Ideally, Montessori knobbed cylinders stimulate and enhance a child’s visual and tactile senses.
Knobbed cylinders are one of the first Montessori materials introduced to children and are one of the first lessons in visual stimulation in the Montessori classroom.
The Montessori Knobbed Cylinder combines 10 wooden cylinders of varying sizes with “knobs” or protrusions that the child can hold to easily manipulate the material. Each knobbed cylinder is placed in its corresponding hole to help the child differentiate and differentiate different sizes.
What does the Montessori Knobbed Cylinders contain?
The Montessori Knobbed Cylinders integrate 10 solid wooden round posts divided into four different types based on their size. The Montessori Knobbed Cylinders also comes with solid rectangular wooden boxes with holes or slots that are the same size as the corresponding posts.
The varying sizes of each knobs allow children to get acquainted with different sizes, develop preliminary skills, understand mathematical concepts, and develop an understanding of complex concepts of weight and size.
There are four variations of the Montessori Knobbed Cylinders that encourage children to learn complex concepts and develop preliminary skills using the built-in error checking feature. Each knob cylinder in this Montessori sensory material varies as follows:
- Block One: Block One varies in height and diameter, meaning the tallest button cylinder will be the thickest in diameter.
- Block Two: Block Two varies in the diameter of each hole.
- Block Three: Like block one, block three also varies in height and diameter, but here the tallest cylinder will be the thinnest in diameter.
- Block Four: Finally, block four differs only in the height of the cylinder.
What is the purpose of Montessori Knobbed Cylinders?
1: What is the primary focus of the first plane of development in the Montessori method?
The Montessori knobbed cylinder is introduced to children at the age of three. The main goal of introducing this wonderful Montessori sensory material is to teach children to visually differentiate between different sizes or dimensions.
The ability to differentiate between different sizes and dimensions is enhanced when children are encouraged to use their sense of touch.
The indirect goal of the Montessori button cylinder is to prepare children for writing by developing fine motor skills by teaching them to use the three-finger grip used to hold a pencil.
The Montessori button cylinder also prepares your child for complex or arbitrary mathematical concepts in the future.
Finally, these engaging Montessori sensory materials help children develop appropriate math vocabulary, introducing words like ‘height’ or ‘diameter’.

- Improves Fine Motor Skills: Grasping the small buttons on the cylinders helps improve hand-eye coordination and fine motor control.
- Promotes Concentration: The concentration required to match each cylinder to its corresponding hole helps develop focus and attention to detail.
- Develops Cognitive Skills: Through trial and error, children learn to distinguish cylinders based on their size and shape, improving cognitive problem-solving skills.
- Promotes Independence: As children master the task, their confidence and ability to work independently are strengthened.
- Prepares for Math Concepts: This activity lays the foundation for understanding math concepts such as size, order, and sequence.
How to Present the Knobbed Cylinders?
Materials
- Four sets of ten graduated cylinders, each equipped with a button for easy handling. The cylinders are designed to fit into corresponding holes on each block.
- In block 1, the cylinders have a variable diameter, extending from 1 cm to 5.5 cm, while their height is uniformly fixed at 5.5 cm.
- Block 2 has cylinders that gradually change in all dimensions. Their diameter extends from 1 cm to 5.5 cm, corresponding to a simultaneous increase in height from 1 cm to 5.5 cm.
- The cylinders of block 3 of vary in diameter, identical to the first two blocks, but have the opposite height, from 5.5 cm to 1 cm.
- Block 4 of provides a study of verticality, the diameter of the cylinder is kept constant and the height alone extends from 1 cm to 5.5 cm.
The following instructions are the basic presentation of Montessori Knobbed Cylinders:
Presentation
Taking Out the Cylinders:
- Start by gently gripping the rightmost cylinder knob, using your thumb and two other fingers for a firm grip.
- Carefully remove the cylinder from its hole, using a firm grip to remove it completely.
- Place the cylinder upright in front of its hole, like a little sentinel guarding its position.
- Move to the leftmost cylinder, using the same grip to lift it up and place it in front of its hole, mimicking the first cylinder.
- Continue with playful randomness, removing each cylinder and alternating their positions to the right and left of the first two weights.
- Once all the cylinders have been removed, gently tilt the block forward to show your child the holes, encouraging curiosity.
Put the cylinders back in place:
Now let’s put each cylinder back in its place.
- Take one at a time, holding the buttons as you did before, and carefully slide them back into the hole.
- Tap the bottom of each hole, making sure each cylinder is in place, just as if you were putting them in a bed.
- Encourage your child to take turns removing and replacing the cylinders, exploring different sizes and adjustments.

Variations & Extentions
Variations
- Present the activity blindfolded, encouraging children to rely on touch to differentiate between cylinders.
- Mix cylinders from different blocks to challenge them to differentiate and match the correct sizes.
- Use the cylinders for a sorting game, where children arrange them based on their size or height.
Extension
- Integrate language lessons by introducing vocabulary related to size, such as “tallest,” “smallest,” “thickest,” and “thinnest.
- Introduce a measuring activity using a ruler to measure the height and diameter of each cylinder.
- Combine the cork cylinders with other sensory materials, such as the Pink Tower or the Brown Stairs, to explore the relationship between size and dimension.
Recommendations
- Make sure children handle cylinders and blocks gently to maintain their condition and reinforce respect for the materials.
- Observe children’s technique and offer tips to improve their grasp and coordination.
- Encourage children to work at their own pace, allowing them to fully engage and absorb the activity.
