These activities refine the various senses.

Color tables are used to develop the chromatic sense. Sound boxes and bells refine the auditory sense and music appreciation. Solid shapes develop stereognostic sense, knobbed and knobless cylinders, brown stairs and the pink tower teach children to discriminate among various sizes and shapes and indirectly prepare the children to learn mathematics and the concept of quantity. These and many other activities are available in each preschool classroom.
