This book is based on many years of lectures and workshops on authentic Montessori classroom practices in over thirty countries. In order to meet the needs of children in Montessori primary and elementary classes, the skill in observation, and keeping records of the children's progress, is essential. The author shares her personal experience, through basic practices and interesting stories, working with children and young adults, from age two through high school, in Montessori environments. The book ends with an enlightening chapter that shares the potential and needs of the adolescent. It is called "Becoming and Adult."
