Several years ago, I created this deriving the unit circle foldable for my trigonometry students to work through and glue in their interactive notebooks. I tweeted about the foldable, but the file never made it to my blog. Today, I am remedying that! We started with a review of our special right triangles. First, we …

A couple of years ago, I created this trigonometry puzzle to keep my students busy when we unexpectedly finished our lesson with more time to spare than I had planned. This trigonometry puzzle is really the Twisted Wires Puzzle by Cliff Pickover in disguise. To keep my students from googling the puzzle (as they have …
This radian arts and crafts activity is designed to help students conceptually understand what a radian is. As a bonus, it creates a beautiful, mathematical art display for your classroom. This is one of my most popular tweets of all time. People come to my blog searching for it frequently, but until today it has …
I created these unit circle magnets to use with my dry erase magnetic unit circle from EAI Education. I plan to use the magnets both as a way to have a large unit circle on the wall of my classroom and for various activities throughout the year. When I share pictures of my magnetic unit …
Several years ago, I created a double angle identities joke worksheet as a promposal when one of my trig students wanted to ask another student in the class to prom. I shared the file, but it was really only useful if you had a student named Sam who wanted to ask another student to prom. …
I created these trig functions posters a few years ago when I was teaching a year-long trigonometry course. Somehow, they never got a blog post of their own. I created separate posters for the three basic trig functions and the three reciprocal trig functions. I designed these posters to print on 11 x 17 cardstock. …
I created this Parts of a Right Triangle poster several years ago when I was teaching trigonometry. I wanted to emphasize the vocabulary words for adjacent, opposite, and hypotenuse before we jumped into right triangle trig. I designed this parts of a right triangle poster to print on 11 x 17 cardstock. I hung this …
I’m here today to share a trig ratios puzzle with you. I’m currently using part of my summer to create some activities for my Pre-Calculus classes for this upcoming year. Last year, I felt like I definitely spent more of my time creating things for my Algebra 2 classes than my Pre-Calc classes. This was …
A few weeks ago, I tweeted about a trig identities matching activity I created. I promised to share the files, so that is what I am doing today. Sorry it’s late! This is a different activity than the trig identity group challenge I shared a couple of weeks ago. In fact, I actually used this …
I created this free printable trig identities cheat sheet for my Pre-Calculus students to reference as we work through our unit on trigonometric identities. I do not require my pre-calc students to memorize the various trig identities. I am more interested in my students being able to use and apply trig identities than to be …
