A note about the Trig Evaluation Puzzles: As with all my concept connection puzzles, this is not intended to teach the concept, but help build a strong understanding of the concepts after it has been taught. In the case of these Trigonometry Evaluation Puzzles, I teach my students to keep the unit circle in mind when evaluating the answer. You may forget the exact answers in the following years, but through a better understanding of the underlying meaning, you can re-build your answers anytime. After you play the puzzles a few times, you just might have them memorized.
