In this unit, we are developing proficiency with trigonometric ratios. There is an introduction to some advanced topics, namely Sine Law and Special Triangles, as well as a lot of arbitrary information.
In Lesson 1, I will be introducing trigonometric functions as coordinates of the unit circle. This will involve a lot of estimation. Most of the class will involve students working through this worksheet at their desks, in groups. Although this isn't ideal, the worksheet is designed to provide Arbitrary knowledge in the hopes that students can uncover the necessary independently. The class will end with a collaborative estimation game, as well as an inquiry based consolidation in which I will try to guide students towards some necessary formula. For an elaboration on the origins of the worksheet, refer to my previous 'Unit Plan Draft' post.
In lesson 4, I'll be providing some historical context for geometry and trigonometric functions. This will feed nicely into the project introduction, which will hopefully engage students and encourage them to think more generally about applications of trigonometric functions. This lesson will conclude with board-work in which students will work collaboratively on a few iterations of one of my favorite puzzles.
In Lesson 5, students will be going outside to take angle measurements so as to measure structures on top of the school. The purpose of this will be to have students appreciate the value of Sine Law.
I've also included the required worksheets (for Lesson 1 and 5), and the project handout / rubric.
Excited to deliver this unit!
