Maria Montessori believed that nothing comes into the mind except through the senses. During the years between three and six, as children develop their senses, their attention is directed toward the environment. The purpose of the Sensorial activities is to help the child in his efforts to sort out the many varied impressions given by the senses. These materials are specifically designed to help the child develop discrimination, order, and to broaden and refine the senses. These materials also help prepare him to be a logical, aware, and perceptive person.
Visual discrimination of difference in dimension, width, length, and size can be found in materials like the Knobbed Cylinders.
The Sensorial materials are designed with a built in feed back to control of error to show when mistakes have been made. The child then remains independent of your oversight and develops an inner, personal incentive to practice and improve. After experiencing Sensorial activities, the child’s sense perceptions will appear inherently structured and capable of comprehending abstract concepts.
