Some of the activities for pre-schoolers outlined here may strike some parents as turgid and artificial -- for example, talking about the texture of a toothpick (smoothness, points, thinness, thickness, etc.) or giving a child a pea, bean or rice grain to drop in appropriate bowls. However Winick's introduction stresses the importance of the five senses, movement, language and fantasy, play in perception, growth and learning -- and the activities described do point up a process by which children realize and conceptualize the world around them. The earnest exercises are presented sequentially and emphasize visual, tactile and motor discrimination and coordination. Whereas the parent or teacher might not care for the models (they are carefully laid out with materials needed, setup and approach, and are quite formal), this book has the not inconsiderable value of focusing on the child's increasing potential to learn about his environment. For many parents this guide could be a stimulus for improvised learning and play.
