HW: Complete Book 13.3

We started with a review of what a radian is and how to convert between degrees and radians, and vice versa.
HW: Complete Book 13.3

Students were given unit circle angle measurements in degrees and radians and were asked to assemble them into a unit circle at their circular tables. Once groups properly identified the angles, they copied this to their 1/2 sheet unit circle. Then we showed how to use our left hand to visualize the first quadrant of the unit circle and calculate the sine and cosine values at 0, 30, 45, 60, and 90 degrees.

HW: WS 13.3 Practice do 1 - 15 (front side) Students used the first half of class to complete a book review before the quiz. Students had 20 minutes to complete the Quiz 13.1 - 13.2.
HW: Complete Book 13.2: page 840 - 842 13 - 25 odd, 41 - 49 odd, 60, 64 - 66 AND page 843 8 - 22 Even We started by checking over WS 13.2 Test Prep together. We collected this packet.
Then we looked at another way to measure an angle instead of degrees. We found that we could describe an angle using the ratio of the arc length to the circle's radius (called a radian). We converted between radian measure and degree measurements (360 degrees = 2 pi radians). We used this fact to create a proportion so that we could determine either the radian measure given the angle in degrees or vice versa.

Quiz 13.1 - 13.2 is tomorrow, May 4th. Today we discussed what is the unit circle and how to find the sine and cosine values for multiples of 90 degrees. We also went over the second page in the packet. Lastly, we completed 10 - 12 Kahoot questions that reviewed angles - which quadrant they were in as well as co-terminal and reference angles.

This will be collected tomorrow, 5/3. We reviewed the vocabulary on angles and showed how to draw positive or negative angles. We also worked on identifying the reference angle from the given angle. Key point is that the reference angle is made with the terminal ray and the x-axis.

Students turned in their practice test chapter 7 (part 3) and completed their last assessment in chapter 7.
HW: Complete the 13.1 packet. This will be collected on Monday, May 1st. Students were given a final practice test for chapter 7. They worked on that in class as I talked with students about their district assessments. During the last 5 minutes we went over questions on the practice test.
HW: Complete the practice test. Test over 7.3 - 7.6 (log equations and log properties) is tomorrow, 4/28. We completed our class notes on periodic functions. We went over the vocabulary of periodic functions, period, cycle, and amplitude. We completed the vocabulary support WS 13.1 and started WS 13.1 Practice together.

The last assessment of chapter 7 will be on Friday, 4/28. HW: WS 13.1 Practice (both sides) Students completed the second district assessment for chapter 7.
HW: Enjoy the day! |
