Warm-up: Clicker Questions

5 minutes

As a warm-up to today’s lesson, I will ask my students to complete the clicker questions located on pages 2-5 of today’s Flipchart_ Application of Right Triangle Trig (p. 1-5). These are very basic multiple choice questions that assess if students can solve right triangle trig problems out of context before we move into problems with context.

You might want to review the video reflection Right Triangle Trigonometry in a Pre-Calculus class if you have questions about how today's lesson fits into the curriculum at my school.

Homework

Assign Homework 5 - Fundamentals of Trigonometry from this unit. This assignment continues the work from class today by having students complete right triangle trigonometry problems in context.
