Trigonometry

I created this finding missing angles of right triangles practice book for my trigonometry students to glue in their interactive notebooks. My students were a bit miffed that they had to just write these equations.  They thought I should have given them a foldable for these! I did make them a practice book, though.  These …

I created this angle of elevation and angle of depression interactive notebook page for my trigonometry students this year. I am trying to give my students word problems whenever possible on their quizzes. So many of the problems involve angle of elevation and angle of depression, so I printed an illustration from Varsity Tutors of …

We created this parts of a right triangle interactive notebook page to start off our unit on right triangle trigonometry. Each student had to cut a right triangle out of colored paper and glue it into their notebooks.  We labeled one of the non-90 degree angles as theta.  Then, we discussed how to identify the …

After making my Periodic Table War game, I had the brilliant idea that a Radians vs. Degrees game would be perfect for my trig students.  After quick google search, I found out this idea was NOT original.   I found a free file on TpT for Radian Degree War.  I downloaded it, and it was …

SOH CAH TOA. The mnemonic device that sums up the majority of the population’s knowledge of right triangle trigonometry. Today I want to share a free download of a SOHCAHTOA Poster I made for my own classroom. Yesterday, I printed off a heap of posters and started laminating them.   Earlier this summer, I had …

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 …
