Have young mathematicians create new identities! They explore the even/odd, cofunction, and periodicity identities through an analysis of tables and graph. Next, learners discover the relationships while strengthening their understanding of the functions.

Instructional Ideas

• Create collaborative groups and allow classes to work through the activities independently
• Have learners start a record of the trigonometric identities studied

Classroom Considerations

• Class members should have a strong understanding of the graph of a sine and cosine function
• The 10th in a series of 19 lessons

Pros

• Uses questioning techniques to lead learners to conclusions
• Provides scaffolding instructions to differentiate

Cons

• None
