The Coloured Cylinders Control Chart — 11×11 Graduated Circle Grid is a Geometric Solids 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.
“The senses, being explorers of the world, open the way to knowledge.”— Maria MontessoriThe Discovery of the Child
“Children display a universal love of mathematics, which is par excellence the science of precision, order, and intelligence.”
— Maria Montessori, The Discovery of the Child
The Cilindros De Colores control chart addresses the child's fundamental need for order and systematic organization during the sensorial period. This 11×11 grid with graduated circles creates a mathematical framework that transforms abstract dimensional relationships into concrete visual patterns. The Roman numeral markers along the left column establish a formal recording system that bridges sensorial exploration with early mathematical notation. When children work with the coloured cylinders, the control chart becomes their reference point for verifying dimensional accuracy and sequence. The graduated circles across the top row provide immediate visual feedback, allowing children to self-correct their cylinder arrangements without adult intervention. This cardstock chart develops the child's capacity for systematic thinking by requiring them to match three-dimensional objects to two-dimensional representations. The grid structure cultivates mathematical readiness by introducing coordinate systems through sensorial experience. The control chart's design respects the child's need for independence by providing a silent teacher that guides verification work. Through repeated use of this reference tool, children internalize concepts of gradation, sequence, and dimensional relationships that form the foundation for later geometric and algebraic thinking.
Each order includes everything needed for proper presentation and long-term use.
Follow the Montessori method of presentation for optimal child development.
Model slow, deliberate movements to emphasize care and respect for materials
Use minimal words, letting your precise movements communicate the process
Use your dominant hand for placement while the subdominant hand steadies the chart
Occasionally step back to observe the pattern emerging, modeling self-assessment
If a child makes an error, wait to see if they self-correct before intervening
Ask 'What do you notice?' rather than pointing out specific features
This randomization ensures the activity remains challenging for repeated use
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.
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”
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.
