Although that is the name of a set of cards we produce, there is a reason for bringing out these activity cards. The mother rarely says Bird, she says Blue bird. We offer a picture on one side with the word on the other. The child will say the color red about six months to a year before learning the actual word. This set of cards is actually a kindergarten year in short form.
Colors seem to be easy to learn for the child.
You touch the shoe. There is something about the child's neuron formation and colors that make an easy fit. Forms, or shapes, are easy for a child to figure. They are like a word. The letter A does look like a triangle.
