Made of high impact styrene, 8-1/2 x 11. This book puts the TrigTrainer manipulative to work as a powerful introductory tool for teaching basic trigonometric concepts. Loadedwith 24 lively activities and a smattering of trig history, this book explores the basic functions and their relationship to the unit circle. The appendix is packed with useful resources that expand the teaching power of the TrigTrainer. 8-1/2 x 11, 80 pages, Appendix.
