TrigTrainerâ„¢ Kit
Grades 7-10. A trigonometric function generator that provides a hands-on approach to the teaching of trigonometry. The NCTM Standards encourage the use of manipulative devices to be incorporated with calculators in the teaching of basic trigonometry. TrigTrainerâ„¢ helps fulfill this basic requirement by allowing students to explore basic relationships of the sine, cosine, and tangent functions with two-digit accuracy. Made of high-impact styrene, it measures 8-1/2 in. x 11 in. The kit also includes an activity book containing 24 lessons as well as a transparent, projectable TrigTrainerâ„¢ for the overhead.
