2.0.4 Working Through Unit 2

As you work through the unit, use some of the ideas mentioned in Unit 1 for learning actively. Remember that taking breaks will be important. You will have to determine how long you can study this material before you need to stop and relax. Be sure to take advantage of all of your resources—friends, family, the Internet.

Pay close attention to how math is written in the unit and how you write the corresponding details in your math notebook. Remember that math is a language, so how we write it really does matter.
