Explore Folding of the Circle: Activity Book 1 is the first in Bradford Hansen-Smith's series of hands-on instructions for folding circles. This book contains the first steps in generating information and some amazingly beautiful and complex forms by simply folding and joining circles.

Because measuring, cutting, and putting pieces together requires some skill and higher level thinking, geometry is not usually taught until the high school level. This book brings the experience of these concepts and functions down to the primary grade level by folding paper plates. All that is necessary is to be able to fold a circle in half, observe, and talk about what you have done.

Hansen-Smith's revolutionary approach delves into the comprehensive nature of the circle and demonstrates the pattern base for the geometric patterns observed in nature. This series of spiral-bound activity guides contains information about art, patterns and design, geometry, crafts, origami, mathematics, and more. Useful in the classroom, homeschooling, or for self-study. Published in 2006 by Wholemovement Publications. 64 pp. ISBN 978-0-9766773-2-1 (0-9766773-2-6)
