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 …
