A couple of years ago, I created this trigonometry puzzle to keep my students busy when we unexpectedly finished our lesson with more time to spare than I had planned. This trigonometry puzzle is really the Twisted Wires Puzzle by Cliff Pickover in disguise. To keep my students from googling the puzzle (as they have …

# Trig Functions

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’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 …

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 …

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 …
