3rd Cylinder Of Block No. 4
Made by Nienhuis Montessori · shipped by Heutink International (Netherlands) About the maker
The third cylinder of block number four, a single replacement piece. Because every cylinder in this block shares a diameter, the sockets differ in depth alone, and a child cannot solve the block by trying pieces until one sticks. Judging height by eye and then confirming it is a later skill than fitting a peg into a hole, which is why block four usually comes last of the four. The complete cylinder block is a separate item.
“Children display a universal love of mathematics, which is par excellence the science of precision, order, and intelligence.”
The 3rd Cylinder of Block No.
- Refinement of pincer grasp through lifting the knobbed cylinder
- Visual discrimination of simultaneous variations in height and diameter
- Development of muscular memory for specific dimensional relationships
- Preparation for mathematical concepts of proportion and ratio

4 exists as a replacement piece, recognizing that individual cylinders may become separated during classroom use. This single wooden cylinder maintains the precise dimensions that characterize Block No. 4, where cylinders vary in both height and diameter simultaneously. The knobbed design of this cylinder serves a specific developmental purpose: preparing the child's fingers for pencil holding through repeated practice of the pincer grasp. When a child lifts this particular cylinder by its knob, they experience the weight distribution unique to its specific proportions. The smooth wooden surface provides tactile feedback that differs subtly from cylinders of other dimensions, training the child's sensorial memory. This replacement cylinder ensures the complete set remains available for children to discover the mathematical relationships between size variations. The precision-cut wooden form allows children to experience how diameter and height change in constant proportion, building an unconscious preparation for later mathematical concepts of ratio and proportion.
How to present it
Follow the Montessori method of presentation for optimal child development.
Place the cylinder on a neutral background. If reuniting with Block No. 4, ensure the block is positioned at the child's dominant side with all holes visible.
- 1
Demonstrate grasping the knob with thumb and first two fingers, lifting slowly to feel the weight
Exaggerate the pincer grasp to make the finger position visible - 2
If matching to Block No. 4, systematically test each hole by lowering the cylinder partially
Listen for the subtle sound when the cylinder finds its matching hole - 3
When the correct space is found, lower the cylinder smoothly until the base sits flush
Run your finger around the rim to verify perfect fit - 4
Lift and replace several times, focusing on the smooth motion
This repetition builds muscle memory for the specific weight and size
