Chapter Two considers the impact of the physical environment on children's behavior and ability to learn and offers suggestions for arranging furniture and materials in the block area. The teacher's role in the block corner is explained in Chapter Three. Chapter Four looks at how blocks can be used to recreate real life settings. The teacher's role in listening, observing, facilitating and supporting dramatic play is explained. The opportunities for learning math skills and for problem solving are presented in Chapter Five. The last chapter demonstrates how to make blocks and discusses other types of blocks and their care. At the end of each chapter there is a list of suggested activities which adults can try including some specific ways to implement the information in their own classrooms.
