Integrated 3 ---Week of Aug 29-Sept 2

Monday, 8/29
We began Law of Sines today --- introduced the law of sines and it's origin. Unfortunately, we didn't have much time to play around with how to use it. We'll tackle that tomorrow. If you missed class, you can find this derivation of the Law of Sines on page 29 problems #2&3.

I assigned HW#7: page 31 On Your Own for homework, but I'm not sure if students will be successful at this time. Please try to do it, but we'll discuss tomorrow and won't turn in this assignment until Wednesday.

Tuesday, 8/30
We continued today with our investigation on how to set up and solve Law of Sines problems.

MathTV Warning/Disclaimer
Often the approach the the teacher on the video takes is not the same as the approach that may have been used in class. This may be helpful, or it may be confusing, so be fore-warned.

BIG IDEA: Find missing information in a triangle given...
1.) 2 angles and 1 side (review from yesterday and Monday)
2.) 1 angle and 2 sides (new learning)

Self-Assess: Students were grouped according to their own self-assessment... need help, need more practice or need advanced practice.
"Need help" groups worked with me.
"Need more practice" groups worked on the first page of the practice page.
"Need advanced practice" groups worked on the second page of the practice page (there are 3 copies per page)
Here is the link to the Practice Page
