In the process of completing my degree in biochemistry, I took various biology, anatomy, and physiology classes and purchased the requisite textbooks for hundreds of dollars. I now teach upper elementary students in a Montessori school. I can use the college textbooks for occasional reference or specific research with the students, but when I need to present an impressionistic lesson or just tell about the human body, this book is the one I go to. It presents the body like a story with simple, clear, beautiful illustrations inspired by the likes of Leonardo Da Vinci. If you are a Montessorian (or any teacher for that matter) looking for a simple, concise reference to supplement lessons on the human body, I would look no further. My co-teacher has used this book for years and has thankfully shared it with me. Get it if you ever find it!
