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 …

## Wheel of Theodorus Bulletin Board

I’m excited to share my student’s creative wheel of theodorus projects which I turned into a Wheel of Theodorus Bulletin Board to decorate my high school math classroom. Every year, I have this plan to change my bulletin boards out throughout the school year.  This year that happened only once.  It also happened way back …

## Gettin’ Triggy Wit It

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 …

## SOH CAH TOA Foldable

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 …

## Pythagorean Theorem Notes

These are the pythagorean theorem notes I used with my trigonometry students in our beginning of year geometry review. We glued these notes in our trigonometry interactive notebooks. The Pythagorean Theorem booklet was stole from the blog of Jessie Hester.  She has a ton of resources for teaching the Pythagorean Theorem!  If I was teaching …

## Special Right Triangles Practice Book

I created this special right triangles practice book for my trigonometry students to glue in their interactive notebooks as part of our beginning of the year geometry review. This was our last topic to review before delving into actual trigonometry.  I don’t know exactly what it is about special right triangles, but I LOVE them. …
