Reflection: Diverse Entry Points Verifying Trig Identities (day 2 of 2) - Section 2: Whiteboard Review


Today’s lesson has great extensions and scaffolds built right into the activity. For our students who are ready to further their knowledge of simplifying trig identities they will have the opportunity to critique other peoples’ work and to learn new ways of simplifying. Encourage these kids to simplify the expressions or verify the identities in more than one way while they wait for others to finish their problem. These students can also take the lead in presenting their solutions and explaining to classmates why they think their method for verifying is best. Encourage students to share if they had a different way of simplying than someone else who presented. Here is an example that I captured of two different methods presented by my students:

Student Work 1

Student Work 2

For our struggling students, they will be supported in their teams if they get stuck and will also have a great opportunity to re-learn the concepts from their peers’ various shortcuts and explanations to simplifying identities. I also find that while the students are working, I am available to provide support to any whole team that is struggling.

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.
