It is important to note that this is a very simplified overview of the Montessori Method, a "primer" (as the title states) for parents who probably know very little about the history of the movement.
I found the information to be to the point and organised in such a way that it summarises the Montessori way naturally. The appendix lists common Montessori tools (with pictures) and their purposes, as well as useful tips for how parents can support and further the Montessori work when at home. This is a great first book for parents just being introduced to Montessori, because it's a concise, clear, and very quick read.
