Reflection: Discourse and Questioning Verifying Trig Identities (day 2 of 2) - Section 2: Whiteboard Review


For today's Whiteboard Review Game, I put a greater emphasis on presenting one's own solution method than finding the ‘correct’ way to work the problem. I really wanted students to try and to not feel nervous about presenting incorrect work in front of the class. Even at this time of the year, many of my students don’t like to present their own work, especially if they have to do it alone. Yet, this is an important skill for students to acquire before they graduate from high school (MP1MP2).

Today, I was willing to let some students bring up a teammate to assist.  Although I did not need to today, I will sometimes present a students' work for them to model how they should do it the next time around. I want the students to believe that their ideas have merit.

Verifying Trig Identities (day 2 of 2)

Unit 9: Trigonometric Equations
Lesson 7 of 16

Objective: Students will be able to verify complex trigonometric identities by using the fundamental trigonometric identities.

Big Idea: Students are given an opportunity to practice simplifying identities while also seeing how their peers approach the problem.
