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 …

Illustrating the Sum of Angles in a Triangle

I created this interactive notebook page to help illustrate the sum of angles in a triangle. Instead of just telling my students that the sum of the angles in a triangle is always 180 degrees (something I hope they remember from geometry!), I decided to have them cut out a triangle and illustrate it themselves. …

Complementary and Supplementary Angles Notes

I created this complementary and supplementary angles notes page for my trigonometry students as part of our beginning of year review before jumping into the actual trig course content. We wrote the following notes in our trigonometry interactive notebooks. Full Disclosure: My students hated this notebook page.  You may think hate is a strong word. …
