I strongly recommend you do more than required. The extra practice problems below are mostly the problems recommended at the bottom of the ASSESSING OBJECTIVEs in the chapter. For example, Assessing Objective 1 on p. 12 of the textbook (see screenshot below) suggests problems 1.1, 1.3, and 1.6.

 

Some notes on homework assignments:
1. Start early, don't procrastinate. The homework assignments are essential in understanding what we cover in class.
2. Turn the homework in on time! You may not receive full credit if it is late.
3. Work with others but turn in your own work.
4. On top of every assignment you must write your name and the CHAPTER number. If this information is missing you may not receive full credit.
5. The homework must be clean, clearly structured and legible. You may not receive full credit if your work is not legible or if I don't understand it. I will not always worry about this but beware that I may. If your work tends to be on the messy side :) you might want to solve problems on scratch paper first and then write it out clean for submission.
6. Box your final answers.
7. If you are stuck on a particular problem or if you feel that something is incorrect, state specifically where and why you are stuck. Often stating the problem helps us find help and solutions.
8. If you don't have time to do all problems state that. Within reasonable limits there will be no deductions.
9. At the top of each assignment, in a different color, explain which problems you have questions on.
