I decided to create a Unit Circle Bingo Game to give my Pre-Calculus students some much-needed practice with evaluating trig functions using the unit circle. Technically, this is more of a game of connect 4 than bingo, but bingo just sounds more fun. So, Unit Circle Bingo it is! Bingo is one of my go-to …

I created this fun quadrants unlocked activity to give my pre-calculus students some much needed practice determining the signs of trig functions in various quadrants. In my many years of teaching trigonometry and pre-calculus, one of the topics that my students have struggled the most with is using facts about one trig function to determine …

Several summers ago, I created a set of printable radian sectors to illustrate what different amounts of radians looked like when graphed in standard form. I had a brilliant idea to make some sort of auction activity where students competed to see which group could create the most complete circles. At least I think that …

I created The Great Quadrant Guessing Game several years ago to give my Pre-Calculus students some extra practice determining which quadrant of the coordinate plane was represented by two trigonometric facts. The Great Quadrant Guessing Game For example, in which quadrant is the sine of an angle positive while the cosine of the same angle …

I created these SOH CAH TOA notes for my Pre-Calculus students a few years ago to review how to find the trigonometric functions of an angle, given a triangle. First, we reviewed the different parts of a right triangle. I have also created a poster of the parts of a right triangle that might be …
