The Coloured Cylinders Control Chart — 11×11 Graduated Circle Grid is a Sensorial Montessori material designed for children aged 3-6, crafted by Nienhuis Montessori to AMI standards.
The Cilindros De Colores control chart is an essential Montessori sensorial material featuring an 11x11 grid with graduated circles across the top row and Roman numeral markers down the left column. This precise reference tool enables children to organize and verify their work with the color cylinders, supporting self-correction and visual discrimination development through systematic arrangement of colored objects by size gradation.
“Education is a natural process spontaneously carried out by the human individual, and is acquired not by listening to words but by experiences upon the environment.”— Maria MontessoriEducation for a New World
“The child is both a hope and a promise for mankind.”
— Maria Montessori, Education and Peace
The Cilindros De Colores control chart embodies Dr. Montessori's principle of auto-education through its self-correcting design. This material supports the child's natural tendency toward order during the sensitive period for refinement of the senses. By providing a visual reference for systematic arrangement, it allows children to independently verify their work, fostering intrinsic motivation and concentration. The chart's precise grid structure appeals to the mathematical mind, while the gradual size progression develops visual discrimination and prepares for later mathematical concepts. Through repeated use, children internalize patterns of gradation and develop the ability to perceive subtle differences, essential for intellectual development. The material respects the child's need for repetition and perfection, allowing unlimited practice without adult intervention.
Each order includes everything needed for proper presentation and long-term use.
Follow the Montessori method of presentation for optimal child development.
Invite the child to carry the materials to a work mat, demonstrating careful two-handed carrying
Show how to unroll the control chart carefully, smoothing it flat with both hands
Select the largest cylinder and place it in position I-1, aligning it precisely with the circle outline
Continue placing cylinders in size order across the first row, pausing to visually compare sizes
Proceed row by row, maintaining the size gradation pattern vertically and horizontally
Upon completion, invite the child to observe the completed pattern from different angles
Demonstrate careful removal of cylinders, returning them to the basket in random order
Every material is carefully selected for durability, safety, and authentic Montessori experience.
The mathematically precise grid layout reflects Montessori's emphasis on order and systematic exploration, allowing children to discover relationships between size, color, and sequence independently.
Each material supports multiple areas of child development simultaneously.
Graduated circles train the eye to perceive subtle size differences, preparing for mathematical concepts of gradation and sequence.
Grid system develops logical thinking and organizational skills essential for mathematical reasoning.
Control chart enables independent verification of work, fostering autonomy and attention to detail.
Roman numerals and systematic arrangement introduce mathematical concepts of sets, series, and notation.
Designed for child-sized hands
Professional tips from AMI-trained guides to maximize the educational value of this material.
“Present this material only after the child has worked extensively with the cylinder blocks and has developed initial size discrimination skills”
Observe without intervening unless the child shows frustration; the control chart allows for self-correction
Note which size gradations challenge specific children and offer indirect preparation through other materials
Rotate different sets of color cylinders weekly to maintain novelty while preserving the same fundamental exercise
Everything you need to know about this material.
The control chart features an 11x11 grid with graduated circles across the top row and Roman numeral markers (I-XI) down the left column, providing a precise reference tool for organizing color cylinders by size gradation.
Children can use the chart to self-check their work by matching cylinder placements to the corresponding grid positions, developing autonomy and self-correction skills without adult intervention.
This material enhances visual discrimination, size gradation recognition, systematic thinking, fine motor control, concentration, and order sense while introducing mathematical concepts through the grid system.
The Cilindros De Colores control chart is designed for children ages 3-6, aligning with the sensitive period for sensorial exploration and when children are developing skills in visual discrimination and ordering.
This control chart works in sequence with other dimension materials like the Pink Tower and Brown Stair, reinforcing concepts of gradation while adding the element of color variation and systematic organization through the grid format.
