Knobless cylinders are a Montessori educational material made of wood that consists of a set of cylinders without knobs or handles. They are used to teach children about size, shape, and spatial relationships through hands-on exploration and manipulation. Knobless cylinders are designed to develop fine motor skills, hand-eye coordination, and cognitive abilities in children. They come in different sizes and can be sorted, stacked, or arranged in various ways to facilitate learning.

Presentation

Introduction

Invite the child to come and work with you. Bring him over to the shelf and tell him we will be working with the knobless cylinders. Show him the red box and have him bring it to the table, placing it on the right side of the table.

Procedure 1: The Red Box
- Open the box and place the box onto its lid.
- Remove all of the red cylinders and place then randomly to the left of the box and place the lid back on.
- Pick up the thickest cylinder and very quietly place it to the left of the table.
- Grade the red cylinders from thickest to thinnest.
- Make sure they are lined up all having the same center point.

- You and the child stand up from the table and look at the cylinders from the top and from every side. (Make sure the child gets to where the table is at nose level to truly see them lined up.)
- Both you and the child sit down and you mix up the cylinders.
- Then have the child grade them.
- Show the child how to put the cylinders back into the box by placing the thickest to the thinnest back in.
- The child can work individually on one box at a time: the red box, the green box, the yellow box, or the blue box

Procedure 2: The Red and Green Boxes
- Take out the red and green box.
- Grade the red as in Presentation 1.
- Take out all of the green cylinders and have the child grade them from shortest to tallest, directly in front of the red cylinders.

 - Look at it from all directions.
- Grade the red cylinders in reverse, and this time in front of the green cylinders so you are now comparing them in the other direction.
- Superimpose one over the other but always keeping the one with the larger base on the bottom.

 - Feel free to explore by superimposing in other ways, always looking at it from all directions.

Procedure 3: The Red and Yellow Boxes
- Repeat as in Presentation 2. Keep the examination orderly but allow the child to explore.

Procedure 4: The Green and Yellow Boxes
- Grade the green and then the yellow cylinders in the same manner as in the above presentations. Allow the child to explore.

Procedure 5: The Red and Blue Boxes

- Superimpose one over the other.
- Allow the child to explore.

Procedure 7: The Yellow and Blue Boxes
- Grade the yellow and then the blue cylinders in the same manner as the presentations before.
- Allow the child to explore.

Procedure 8: Three Boxes at a time
- Have the child begin by grading each of the three boxes and then exploring as he had done when using two boxes.

Procedure 9: Four Boxes at a time

you might what to allow the child to build all four of the sets on a large mirror so as to be able to see the different grading as a reflection.
