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 …
I created this Verifying Trig Identities Worksheet for my Pre-Calculus students to have some extra practice during our unit on trigonometric identities. Students are asked to verify each trig identity. More specifically, they are to show that one side of the equation is equivalent to the other side of the equation. Students must show each …
This past week, my pre-calculus students have been tackling verifying trig identities. I came down with a cold Sunday night, took Monday off at the insistence of my husband, and suffered through the rest of the week. Introducing trig identities while sick and lacking energy/motivation on Tuesday was not my best and brightest idea. So, …
A promposal including a double angle identities worksheet? Read on for details! I’ve never really understood the big idea behind promposals. Part of that probably has to do with the fact that I never went to prom in high school. But, I recently got the chance to be a part of one, and it was …
After years of seeing other teachers share pictures of the unit circle projects their students created, I decided to finally take the plunge. I assigned my trig students the task of creating a visual representation (2d or 3d) of the unit circle in lieu of a semester test in trigonometry. A nice side effect of …
Thursday night, I tweeted about cutting and laminating cards for a leap frog game in trigonometry. I learned about the leap frog game at the OCTM (Oklahoma Council of Teachers of Mathematics) Summer 2016 Workshop. It was at a session titled, “Taking the Practice Out of the Worksheet.” Since, there’s a 99.9% chance you weren’t …
I created this finding trig functions through a point practice book to give my trigonometry students practice finding the sine, cosine, and tangent of a point on the coordinate plane. This put together so many of the concepts we had learned in this unit and the previous unit. It’s so exciting to see all of …
I had my students create this foldable to help them remember the signs of trig functions in each quadrant. We glued the resulting foldable in our trigonometry interactive notebooks. They were quick to ask how they should do this? I simply told them to pick a point in that quadrant and find the sine/cosine/tangent value. …
I created this reference angles foldable for my trigonometry students to glue in their interactive notebooks. The first image I gave students as a reference was from TutorVista.com. The second image I gave my students was from RegentsPrep.org. On the inside of this booklet foldable, I had students sketch the angles (given in both degrees …
After using our angle spinner to learn about sketching angles in standard position, we created these two sketching angles in standard position practice books to glue in our trigonometry interactive notebooks. We did the practice book for sketching angles in standard form with DEGREES first. I did this because students are most comfortable working with …
I love this clinometer activity for giving my trigonometry students extra practice finding missing angles and sides of right triangles. Plus, it answers the question of “When will we ever use this?” I printed a clinometer template off of VirtualMaths.org for them to use. I mistakenly assumed that they would be able to put together …
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 …
