The most fun and exciting learning is, without a doubt, through play. For this reason it is important to remember to conceive toys that stimulate the cognitive development of children. For this exercise I chose the ages of 1 to 3 years. The toy I will design is Tower construction, and what I want to do is draw the attention of the little ones with bright colors and to be able to do it in a special way I want to add different animals. It would be 3 cubes in one, the head, in the second the body and in the third the feet.
