Pedagogs tell us that the plays of children under seven or eight
are noncompetitive and noncooperative. Kindergarten children
play side by side or in pairs, rarely spontaneously in groups.
They are gregarious rather than social. The plays between the
ages of seven and twelve are social, cooperative and competitive
games, but each child usually plays for himself. After twelve
group games with opposing sides are more popular, and finally
tend to crowd out all others.
