During the first 10 minutes of class today, Students will be taking their homework quiz over worksheets #1-3: Homework Quiz #1-3. The clicker version of the homework quiz is located on page 6 of Flipchart_Using the Unit Circle Day 1 and 2.flipchart
For the next part of class, students will have a few more minutes to finish yesterday’s handout, Student Handout - what does the unit circle tell us. My students struggled a bit with question 4d. I tried to lead students to the answer by having them write A, S, T, and C around the quadrants and then think about what a, b and c was asking. If I found that students were spending too much time here, I would just give them the answer. To me, it isn’t really important that they figure this mnemonic device out on their own, but rather just know how to use it.
After students have completed their handout from yesterday's lesson, I want to get a sense of how well students understand the evaluation of trigonometric functions for negative angles and angles that exceed 360 degrees. I also want to assess their current understanding of finding tangent values. To informally gain this information, I plan to have students answer the clicker questions on pages 7-12 of today’s flipchart: Flipchart_Using the Unit Circle Day 2.pdf (PDF pages 3-8).
Page 13 of Flipchart_Using the Unit Circle Day 2 (Page 9 in PDF version) summarizes the key concepts from today’s learning. I encourage my students to copy these key ideas into their math notebooks as a reminder. Then, I asked students to extend their knowledge by completing the questions on Page 14 of the flipchart (PDF page 10) as a closure activity.
I will assign Homework 4 for homework this evening. Students will also be encouraged to start memorizing the unit circle and ways to quickly evaluate the six basic trigonometric functions. I announce that we will have a quiz two class periods from now.
