The Sensorial area builds on some of the basic skills developed in the Practical Life exercises such as precision, attention to detail and concentration. The Sensorial Area offers the child the opportunity to interpret his world intelligently by refining his senses during that period of life between three and six when there is a natural inclination to perfect the sense due to the Sensitive Period for the Refinement of the Senses. This experience enables the child to distinguish and classify his impressions through the specially designed materials. In the Prepared Environment, the Sensorial Area provides a series of exercises with scientifically designed objects that are grouped together according to their physical qualities such as size, shape, colour, texture, weight, temperature, sound etc. This organization of scientific material enables the child to rediscover his environment using his senses in a clear, meaningful and intelligent manner.
