We have added to The Montessori Series this small volume with 11 lectures in which Maria Montessori gives parents an introductory explanation of her vision on education. There always has been a great need on the part of the parent to be as knowledgeable as possible about child development and the essence of Montessori education. Maria Montessori never underestimated the role of the parent, which is why she wrote special lectures for parents during courses and congresses. Recently we found in the pedagogical Archives of Maria Montessori an unpublished coherent set of small writings addressed to parents. We added a small biography of Maria Montessori for those parents who do not know her. Paula Polk Lillard, the internationally respected Montessori author, wrote the Foreword, in which she describes her transition from a traditional public school teacher to a Montessori mother, teacher and trainer.
