Delivery time: 8-12 business days (International)
Designed to accompany any trigonometry text, this userfriendly activities book encourages a visual understanding of trigonometric concepts. Group projects in every chapter help generate discussion, develop cooperative learning skills, and promote alternative assessmentdesigned to help students realize that the way they individually see a problem is not the only way to approach it.Calculator explanations are found in Chapter 0, "Calculator Orientation", and are incorporated into the text as needed. They are presented in a "button pushing" format rather than a "menu name" format to make it easier for students to locate "hidden" key strokes.
