Karplus and Lavatelli observe and discuss children's different approaches to the performance of tasks dealing with quantity, length, area, and volume; and "Growth of Intelligence in the Preschool Years" (1974), in which Dr. Lavatelli narrates the activities of children as they perform tasks that reveal how intellectual thought develops and manifests itself in early childhood.
