  A trigonometric function generator that
provides a hands-on approach to teaching
trigonometry. The NCTM Standards
encourage the use of manipulative devices
to be incorporated with calculators in the
teaching of basic trigonometry. TrigTrainer
helps fulfill this basic requirement by
allowing students to generate the basic
relationships of the sine, cosine & tangent
functions with two-digit accuracy. Made of
high impact styrene, 8-1/2 x 11.
|  The TrigTrainer - A Hands-On Approach to Teaching TrigonometryThis book puts the TrigTrainer manipulative
to work as a powerful introductory tool for
teaching basic trigonometric concepts. Loaded
with 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, grades 8-12.
