This post about the unit circle paper plate activity is more a reminder for me the next time I teach trig than anything else. I’m teaching statistics again next year, by the way. And, I’m doing INBs with my students instead of using the textbook like my first go at teaching stats. I’m super …

I used this evaluating trig functions square puzzle recently with my trigonometry students. We glued our completed puzzles in our interactive notebooks. This puzzle was created and shared by NCTM Illuminations under the name “Trigonometry Square.” While I liked the idea of this puzzle, my students struggled with the fact that there were too many …

I put together these finding trig ratios using the unit circle notes for my trigonometry students to write in their interactive notebooks. We completed these notes after gluing in a copy of the unit circle and a chart of trig ratios in the first quadrant.

My trigonometry students used our unit circles to fill out this trig ratios in the first quadrant chart. We glued the resulting chart in our interactive notebooks to reference throughout the rest of our unit. I edited the file to pre-type some of the information to make the note-taking process go smoother and faster in …

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 …
