Reflection: Intervention and Extension Coterminal and Reference Angles - Section 2: Reference Angles


In teaching this lesson I had a few students who struggled to work with with fractional expressions for radian angle measures. I demonstrated how to make one or two calculations. I tried not to make working with fractions a big deal, but I expect my Grade 12 students to be able to work with fractions. If necessary I quickly review skills with a student, but a student that needs more help must get help outside of the classroom.

I hope that the students will be more proficient with fractions as the Common Core is more consistently implemented throughout the K-12 curriculum. At this point I still adjust my teaching to accommodate student needs.

Coterminal and Reference Angles

Unit 7: Trigonometry as a Real-Valued Functions
Lesson 4 of 13

Objective: SWBAT describe the measure of angles as rotations in the coordinate plane.

Big Idea: What happens when we have angles more than 2*pi or 360 degrees?
