TextbookAlgebra: A Graphing Approach
by Hubbard & Robinson
ContentThis textbook is used for two quarters (Math 091 and Math 092). In this course we will study almost all of chapters 1-6, concentrating on aspects of algebra that are linear (related to straight lines). On the average we will cover more than one section per day, moving quickly through early material so that we can slow down a little on more demanding topics that come later. Applications (word problems) will be a significant part of this course. Some material that is not covered explicitly in the textbook will be presented in class.
PrerequisitesWorking knowledge of basic arithmetic, including fractions, decimals percentages and their applications. Calculators are required. GRAPHING CALCULATORS (TI-82) are recommended.
Daily AssignmentsThe following activities may require three hours each day.
1. Attend class.
2. Study the textbook.
3. Ask questions. Explain out loud or in writing.
4. Reflect on the work you do.
5. Solve lots of problems. (See below.) These will NOT be collected.
Extra helpThere is nothing wrong with getting stuck; it happens to all of us. Butting your head against a stone wall is even good for you in small doses. Though you shouldn't run for help at the drop of a hat (or a crumby little minus sign), don't let things get desperate. There is lots of support available.
1. Classmates; study groups
2. Me
3. Math Lab in C204
4. Solutions manual in Library
5. Weekly help sessions (schedule to be announced)
ExamsFifty-minute midterms are worth 100 points each.
Monday 10/13
Monday 11/3
Monday 11/24The two-hour departmental final is worth 100 points.
Tuesday 12/9
QuizzesEvery week that we don't have a midterm, we will have a 20-minute quiz worth 20 points. Your best six quiz scores will count toward your final grade.
Monday 9/29
Monday 10/6
Monday 10/20
Monday 10/27
Monday 11/10
Monday 11/17
Tuesday 12/2
In-class assignmentsApproximately once each week, unannounced, you will be asked to assemble in teams of 3 or 4 people and complete an assignment in 20-30 minutes of class time. Each assignment will be worth six points, and fifty of these points will count toward your final grade.
There will be no make-up exams, quizzes or in-class assignments!
However, one of the following, a low midterm exam score or a missed midterm exam or a low quiz total, may be compensated for by increasing the value of the final exam.
All exams and quizzes will be comprehensive.
GradesA > 90% > B > 80% > C > 70% > D > 60% > F
A letter grade may be augmented with a 'plus' or 'minus' (+/- = .3gp).
Friday, 11/7, is the last day that you may withdraw (grade = W).
CHEATING POLICY Cheating includes copying answers on tests or assignments, glancing at nearby test papers, swapping papers, stealing, plagiarizing, and illicitly giving or receiving help on exams or assignments -- in short, presenting another's work or ideas as your own. You are expected to conduct yourself with integrity. When you cheat, or aid someone else in cheating, you violate a trust.
If you cheat, the following actions will be taken.
If you feel you have been unfairly accused of cheating, you may appeal.
- You will receive a grade of 0 on the work on which the cheating occurred. This grade cannot be dropped.
- A report of the incident will be sent to the Dean of Students, who may file the report in your permanent record or take further disciplinary action such as suspension or expulsion from the college.
(See WAC 132H-120 for a description of due process.)
