During this refinement, the child can explore more deeply, giving her a higher consciousness of her surroundings.
The sensorial materials and activities are an aid to the refinement of the senses, helping to clarify the information that the sense organs provide. The child will use the sensorial materials to explore areas such as color, texture, sound, geometric pattern and shape, dimension, and size.
The young child has a natural tendency to sort and classify. This is a vital process that allows the child to build his intellect. The sensorial experiences of seeing, hearing, touching, smelling and tasting give the child a concrete experience that will aid later abstract thought. The young child makes broad classifications, but through work with the sensorial materials, each child begins to see finer and finer distinctions. Instead of having a vague understanding of the environment, the child absorbs it deeply. The materials aid the child in developing precise and orderly concepts, and in making comparisons and judgments.
The process of abstraction does not occur earlier with a child who works with sensorial materials, but it does make the connections between the concrete world and the abstract concept clearer because they have a precise picture in their minds. There is a long period in which the child is particularly sensitive to refinement of the senses (birth to age 5). During this period, the child is acutely aware of all things sensorial. They want to explore with their senses, using their whole body. This special fascination with the concrete sensorial world diminishes at age 5, as the child moves into a period of greater abstraction using their ability to classify and imagine. The foundations laid with the sensorial work assist in the movement toward abstraction.
