I titled this unit circle interactive notebook page “Our Trig BFF” since that is how I hope my trigonometry students will feel about the unit circle by the end of our unit. I’m not sure my students just realized how familiar they were going to become with the unit circle! In retrospect, I would have …

This is my first year teaching trig, so I’m figuring out a lot of things as I go. There is no textbook. No pacing guide. Just my own experiences with taking trig in high school to guide me. This is both exciting. And scary. My memories of high school trigonometry involve lots of graphing on …

I created this reference angles interactive notebook page for my trigonometry students. I stole the bowtie idea off of pinterest. Reference angles are always part of the “bowtie.” I’ve also reformatted this page of notes as a Reference Angles foldable. You can give your students some much-needed practice with reference angles using my Trigonometry Reference …

I created this coterminal angles card sort activity for my trigonometry students to complete and glue in their interactive notebooks. Students have to sort the angle cards into groups that are coterminal with one another. Then, they must take a blank square and write an additional angle that was coterminal with the other angles in …

This angle spinner for sketching angles in standard position is one of my favorite pages in our trigonometry interactive notebooks. I had students cut out the initial side and terminal side for their angle out of card stock. The initial side was glued down on the x-axis. The terminal side of the angle was attached …

I created this converting between radians and degrees foldable for my trigonometry students to glue in their interactive notebooks. This ended up being a much-referenced foldable! Outside of Radians to Degrees and Degrees to Radians Foldable: Inside of Foldable: Close up of radians to degrees notes/examples: Close up of degrees to radians notes/examples: Now that …

I created this hand-on exploration for my trigonometry students to explore the question “What is a Radian?” I don’t ever remember really learning what a radian was when I took trig in high school. I’m sure my teacher told me, but I guess it didn’t really stick. We’re going to be dealing with radians a …

I created this practice book to give my trigonometry students practice finding trig ratios of ordered pairs. I think I could have done a better job of writing out these steps. Maybe next time I teach trig I will make these steps clearer… We took a piece of graph paper and folded it into a …

I learned about the song Gettin’ Triggy Wit It by WSHS on YouTube from Meg Craig. It was the perfect addition to our unit on right triangle trigonometry. If you haven’t seen this video, stop everything and watch it now. My students enjoyed the video the first time we watched it, but they had a …

I created this SOH CAH TOA foldable for my trigonometry students to glue in their interactive notebooks. Our geometry standards include basic right triangle trig, but I’ve found that my students’ experience with this topic is greatly lacking. They remember learning SOH CAH TOA, but they never really did know what they were doing. It’s …
