Your students have learned all of their identities, but how do they use them? Give them a circuit and put them to work. Some of the questions involve simplifying, some involve re-writing, some involve solving, etc. 24 questions total. Student must hunt for their answer to advance in the circuit. My students love this format -- they don't leave my classroom when the bell rings!
This circuit is meaty -- it might take two days or an entire block. The teacher should work the circuit first before giving it to the students, but that is the only prep needed.
Enjoy watching and listening to your students as they engage with trigonometry!
