Activities in this area provide the means for the young child to explore the world through their senses.  The world as a whole is compromised of patterns, symmetry and order.  The child may learn to discriminate and match sounds, smells, textures, or colors.  The pre-primary child may grade a series of ten cubes into a pink tower or discover that two triangles combine to form a square.  Such exercises introduce the child to the greater order of the world and provide a necessary base for further study in math and science.
