Sensorial material lies at the heart of the Montessori method: a set of tools designed to help the child explore the world through the senses, refine perceptions and build, at their own pace, an autonomous mind.
An environment that supports development
Every human being carries within them the potential needed to flourish, provided they grow up in a suitable environment. For the child aged three to six, this means offering a setting that responds to the sensitive periods they are going through. During this crucial phase of sensorial refinement, Montessori material, both carefully built and precisely calibrated, is designed to develop the child's capacity for assessment and discrimination. Created to capture attention through its distinctive shapes, it guides the child toward a conscious exploration of the world.
Development through the senses
The Montessori method uses sensorial material to support the child's overall development, both physically and in the refinement of their perceptions. For example, the baric tablets allow the child to assess their environment with greater precision, giving them the keys to take ownership of it more fully.
This material is generally offered from the age of three, but it is essential to respect each child's pace: there is no point in presenting it to a child who is not yet able to concentrate on an activity.
An intelligent approach to reality
Through handling sensorial material, the child develops a sharper and more accurate perception of the world. Each tool acts like a key opening a door to understanding. Take the cylinder blocks: it is not simply a matter of putting cylinders "in" or "out," but of learning to match each cylinder to its socket, discriminating between pairs with care.
For Maria Montessori, sensorial material represents a response suited to the child's development, offering autonomous means of grasping their environment. Sensorial material works like an alphabet: it allows the child to read their environment with growing precision, and gives them the ability to:
- Order their perceptions
- Catalogue sensorial information
- Recognise similarities and differences
- Compare their observations
- Organise their thinking independently
The foundation of sensorial material
The design of sensorial material rests on the search for similarities and differences. This process leads the child to:
A concrete example with the cylinder blocks
First step: the child distinguishes in order to make pairs.
Second step: the child refines by establishing a gradation.
Language lesson: a name is attached to the perception, not to an object but to a concept. The child generalises.
With the red rods, for instance, we don't say "this is the long rod, this is the small rod," but "this is short, this is long." Naming the concept allows for transposition: the child internalises a relationship that they can apply in other contexts.
The 5 characteristics of Montessori material
It isolates a quality
Each material focuses on a single characteristic. The pink tower, for example, is entirely pink: a single colour that draws attention to dimension. Isolating the quality makes the concept easier to grasp and introduces the child to sorting and analysis.
It reveals the error
The material signals the error by itself. With the pink tower, the control is visual: the child sees for themselves if the order is not respected. This control of error is a form of self-education that fosters reasoning and independence.
It is aesthetic
The material should attract, inspire the desire to handle it and awaken interest through its beauty and harmony.
It leads to activity
Each tool offers the child the possibility of self-activity, presented at the right moment according to their development.
It is limited in quantity
The material is offered as a single example. Pedagogically, too many objects kill activity and concentration. Socially, this teaches the child to defer their desires, to respect the work of others and to assert their own choices.
From self-confidence to autonomous thinking
While practical life exercises aim to build self-confidence, sensorial material guides the child toward autonomous thinking. It lets them experience concepts concretely: small / large, light / heavy, smooth / rough…
As Line Lawrence stressed in her lecture "To have or to be," it is essential not to use the material in a didactic way, which would bring us closer to "having" and further from "being."
"School should be a place of being, of becoming fully human, where the inner freedom of every child is founded." After Maria Montessori
