"A massive and most important study. . . . All teachers of young children should know the general outline of the work." -Evelyn Lawrence, British Journal of Educational Studies

Professor Piaget discusses a set of investigations he and a team of co-workers carried out on the genesis of the notion of number in the child's mind.

This volume from Piaget's laboratory in Geneva deals primarily with the development of notions of measurement and geometrical concepts like coordinates, angles, and areas. It is a companion piece to The Child's Conception of Space.

When first published in 1923, this classic work took the psychological world by storm. Piaget's views expressed in this book, have continued to influence the world of developmental psychology to this day.
