Description …Schuberth’s presentation is fresh, lively and artistically wonderful. I can’t imagine a student not discovering one thing after another to be interested in and pursue, this is just so packed with the spirit of joyful discovery. Teachers and parents who use it to guide their middle school students along the pathways of geometric proof will be offering them a lifetime of of interest in logic and spatial relationships. This book is a gift. — Waldorf Books This book is another in Ernst Schuberth’s fine series of books on mathematics in elementary school. Profusely illustrated with geometric drawings, this book is a valuable resource for any sixth-grade teacher and anyone interested in exploring the depths of the Waldorf mathematics curriculum.
