## Mathematical Promposal Double Angle Identities Joke Worksheet

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 …

## Unit Circle Projects

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 …

## Exact Values of Trig Functions Leap Frog Game

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 …

## Finding Trig Functions Through a Point Practice Book

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 …

## Signs of Trig Functions in Each Quadrant Foldable

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. …

## Reference Angles Foldable

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 …

## Sketching Angles in Standard Position Practice Books

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 …

## Clinometer Activity and Foldable

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 …

## Finding Missing Angles of Right Triangles Practice Book

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 …

## Angle of Elevation and Angle of Depression INB Page

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 …
