Folding the Circle: Book 2 $15.50

Explore Folding of the Circle: Activity Book 2 is the second volume of Bradford Hansen-Smith's series of hands-on instructions for folding circles. This book expands on the material in the first book and takes the reader into new territory.

While other approaches to teaching geometry are geared toward the analytical and from traditional static modeling, 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.

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.

We use the cheap fluted edge 9" paper plates for the circles to construct our models. Just flatten the plates with your hands and fold! Some kids like to color them first.
