A fun, interactive review game that reviews Precalculus trigonometric concepts such as radians, the unit circle, trig functions, and vectors. Designed to take 2 45-min class periods or one 80-90 minute time block. Trivia scoring sheet sold separately (or available in bundle for just a dollar more). You'll also want to have plenty of slips of scrap paper cut out for teams to write and submit their answers. I usually give about 1-3 minutes per question (depending on difficulty) and play music during the allotted time to help set the mood.
