Reflection: Adjustments to Practice Even Odd Identities - Section 2: Developing Even Odd identities

 

When my students were working on the Even and Odd Functions worksheet, I got a lot of questions about what is meant by the terminal side of and angle. The questions led me to conclude that my students did not do not have sufficient experience drawing angles in the coordinate plane.  In this case, I decided that I may not have been using the terminology as often as needed for the students over the course of the year.  Thus, I made a mental note to review my lessons in previous units to make sure I include drawing angles in standard position at appropriate points along the way.

I also began to wonder if my students understand that we identify the the terminal side of the special angles on the unit circle. Another question I have is if the students understand what we did in Unit 4 when we found the trigonometric values when we were given on ordered pair. I will work on some of these issues this summer as I plan for next year.
