I created this fill-in-the-blank unit circle chart for my pre-calculus classes to use as they practice constructing the unit circle from memory. Students are given a blank unit circle with the following instructions: Place the degree measure of each angle on the unit circle in the provided circles. Place the radian measure of each angle …
This parent graphs of trig functions clothespin matching activity has been in the making for multiple years. Several years ago, I discovered a Parent Graphs of Trig Functions Worksheet from Robyn Wolfe of Carlisle Schools. Overview of Activity I used the worksheet with great success in my pre-calculus class, and I remember writing a note …
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 …
Several years ago, I created this trigonometry calculator skills pop quiz to give to my Pre-Calculus students before we learn to use our calculators for evaluating trig functions. Students tend to think that these calculator-based problems are super easy and that they don’t need to be taught how to type trig functions into their calculator. …
