This is the authoritative book written by Montessori to describe her methods. It gives an overview of the Montessori Method as developed for 3 to 6 year olds. It is a short work, intended as a manual for teachers and parents, detailing the materials used as well as her philosophy in developing them. "As a result of the widespread interest that has been taken in my method of child education, certain books have been issued, which may appear to the general reader to be authoritative expositions of the Montessori system. I wish to state definitely that the present work, the English translation of which has been authorized and approved by me, is the only authentic manual of the Montessori method ..." M. Montessori in the Preface
