Instructions

1. Read your assigned section and take notes for yourself.

2. Decide with your group how to best summarize the material for the class in short notes. I suggest maybe white paper that can be put under the doc cam for class Thursday. (I will also take pictures and upload to website).

3. Work through a practice problem or two or suggest where practice problems can be found. (tell us which numbers on what page help us practice your assigned topics)
