It makes little sense to spend a month teaching decimal fractions to fourth-grade pupils when they can be taught in a week, and better understood and retained, by sixth-grade students. Child-centeredness does not mean lack of rigor or standards; it does mean finding the best match between curricula and children's developing interests and abilities.

Friendships in childhood are usually a matter of chance, whereas in adolescence they are most often a matter of choice.

Much of the pressure contemporary parents feel with respect to dressing children in designer clothes, teaching young children academics, and giving them instruction in sports derives directly from our need to use our children to impress others with our economic surplus. We find "good" rather than real reasons for letting our children go along with the crowd.

Decades of research has shown that play is crucial to physical, intellectual, and social-emotiona l development at all ages.
