Found a cool new book while web browsing on Amazon. Swirl by Swirl, Spirals in Nature, is a beautifully written and illustrated book that is chock full of spirals, some that surprised me. I read the book to my Kinders and then we decorated a snake pattern/template. This lesson has so many great components: teaching spirals, cutting on curved lines, creating texture on the snakes. The kids had fun "bouncing" the snakes after they were cut out!
