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 no idea how I wanted to decorate my new classroom. I looked on pinterest for ideas, but it seemed like I just kept seeing the same things over and over, and I wanted something new.
A couple of weeks ago, I found out that I am for sure teaching trig again this year. We offer one class above Algebra 2, and this will make the 4th year that we’ve alternated between Stats and Trig. I’m super excited about getting to teach trig again, so that has been influencing a lot of my poster making.


I designed two large posters of the three basic trig function formulas and the three reciprocal trig function formulas, but I haven’t been able to print them because the copy machine at school is not playing nice. 🙁 (This is just a sneak peek of these posters. I’ll blog about them and post the files when I can show you what they look like on the wall of my classroom!) I still wanted to create a SOHCAHTOA poster to jog students’ memories.
I chose to print SOHCAHTOA over three pages so it will be able to be seen all the way across the classroom.
If you download the editable Publisher file, you’ll need to download the free Font Agency FB or substitute your own favorite font. I chose this font because it’s tall, skinny letters let me take up the majority of the page with my text. If you download the PDF file, there’s no need to worry about the font because it will be embedded.

I love the trig posters! I'm going to be student teaching next semester so I won't have my own classroom to decorate just yet. Even if I don't teach Geometry after graduating, I want to use the other poster ideas you've posted on your site!

Whitney Bass wbass@dalecountyboe.org Hey! I have stalked your blog ALL summer! You are a great teacher and I can only hope to be as a great as you! Anyhoo, I want to play Witzzle with my students and have been unsuccessful in getting my hands on the game. I went to all of your links and even searched several websites myself and nothing came of it. Is there anyway that you could help me get this game? If not, that's okay! Thanks for all your knowledge and advice! Hope you have a great year!
