Purchased games and toys have little relevance to healthy child development. Play, however, plays a predominant role in healthy child development. Play that is child-initiated, child-controlled, and open-ended allows and encourages children to process information and to make sense of their world. Basic plain shapes & forms surprisingly open the gates to infinite possibilities in a child's world. Kids can give meaning to even the most basic of shapes and forms.
