As a warm-up for today. I am going to have students complete a Homework Quiz over Worksheets #4-6 from this unit.** This quiz is a sampling of questions selected to quickly assess student’s current progress and gain some insight into how thoroughly students are completing their assigned homework.

** If you have personal response systems the quiz is programmed into the HW QUIZ #4-6.flipchart, page 1.

The ambiguous case of the Law of Sines is always a difficult topic for me to teach. My students really struggle with this concept. In the past I have employed Direct Instruction from a PowerPoint with mixed success. This year, I chose to use a video from TeacherTube that I think really helped my students to stay engaged and better understand the concept for my classes later in the day. I presented Slides 1-6 of the Law of Sines Ambigous Case PowerPoint, then I played the video. From this point, I jumped to Slide 14 and I finished the lesson by having students work the example problems.
