The child's first introduction to color is a box containing six tablets--two red, two blue and two yellow. All the other tablets are the same size, shape and texture. They differ only in highly contrasting color. In this exercise, the child pairs the tablets and learns the corresponding names. This is a simple exercise used for the very youngest children in the class.
The difficulty of the exercise can be increased by gradually adding more pairs of colors. Eventually, the child should be able to match and name eleven different pairs.
