Introduction to Sensorial
What is Sensorial Work
Sensorial comes from the words sense or senses. As there are no new experiences for the child to take from the Sensorial work, the child is able to concentrate on the refinement of all his senses, from visual to stereognostic.
The Purpose of Sensorial Work
The purpose and aim of Sensorial work is for the child to acquire clear, conscious, information and to be able to then make classifications in his environment. Montessori believed that sensorial experiences began at birth. Through his senses, the child studies his environment. Through this study, the child then begins to understand his environment. The child, to Montessori, is a “sensorial explorer”.
Through work with the sensorial materials, the child is given the keys to classifying the things around him, which leads to the child making his own experiences in his environment. Through the classification, the child is also offered the first steps in organizing his intelligence, which then leads to his adapting to his environment.
Sensorial Exercises were designed by Montessori to cover every quality that can be perceived by the senses such as size, shape, composition, texture, loudness or softness, matching, weight, temperature, etc. Because the Exercises cover such a wide range of senses, Montessori categorized the Exercises into eight different groups: Visual, Tactile, Baric, Thermic, Auditory, Olfactory, Gustatory, and Stereognostic.
In the Visual Sense Exercises, the child learns how to visually discriminate differences between similar objects and differing objects.
In the Tactile Sense Exercises, the child learns through his sense of touch. “Although the sense of touch is spread throughout the surface of the body, the Exercises given to the children are limited to the tips of the fingers, and particularly, to those of the right hand.” (Montessori, Maria (1997) The Discovery of the Child, Oxford, England: Clio Press) This allows the child to really focus on what he is feeling, through a concentration of a small part of his body.
In the Baric sense Exercises, the child learns to feel the difference of pressure or weight of different objects. This sense is heightened through the use of a blindfold or of closing your eyes.
In the Thermic Sense Exercises, the child works to refine his sense of temperature.
In the Auditory Sense Exercises, the child discriminates between different sounds. In doing these different Exercises, the child will refine and make him more sensitive to the sounds in his environment.
In the Olfactory and Gustatory Sense Exercises, the child is given a key to his smelling and tasting sense. Although not all smells or tastes are given to the child in these Exercises, the child does work to distinguish one smell from another or one taste from another. He can then take these senses, and apply them to other smells or tastes in his environment.
In the Stereognostic Sense Exercises, the child learns to feel objects and make recognitions based on what he feels. “When the hand and arm are moved about an object, an impression of movement is added to that touch. Such an impression is attributed to a special, sixth sense, which is called a muscular sense, and which permits many impressions to be stored in a “muscular memory”, which recalls movements that have been made."((Montessori, Maria (1997) The Discovery of the Child, Oxford, England: Clio Press)
The Designed Material
Montessori’s materials for the Sensorial work came from her own observations and from ideas and materials from the French doctors Itard and Seguin. Unlike the material used for Practical Life, this material has either never been seen or never been used by the child in his everyday life. With this said however, the child will receive no new experiences through the use of the material. This was purposefully thought through in order to give the child what he knows, but might not yet realize, and to then refine his knowledge. In order to do this, the material is presented in a specific way or in a specific pattern: the child learns to match the similar things, then he is shown how to grade the material based on its quality, and then he receives the language related to his work. In presenting the material to the child in this way allows him to fully understand the concept of his work.
