### Learning Objectives

After completing MAT 003 students will

• Perform arithmetic with signed numbers and fractions.
• Translate sentences into equations with variables.
• Use the distributive law to transform expressions.
• Solve simple linear equations.
• Model realistic problems with simple linear equations.
• Solve small systems of linear equations.
• Graph linear equations and inequalities.
• Calculate slopes of lines and understand what they mean.
• Find an equation for the line given two points on the line, or one point and a slope.
• Translate applied problems involving geometry into computational problems involving a variable, and find the solution.
• Add, subtract, multiply, and divide polynomials
• Use and understand integer exponents (including negative exponents).
• Factor by grouping or patterns and factor trinomials.
• Solve quadratic equations by factoring.
• Verify solutions to applied problems.

### Computers and Calculators, Computer Literacy

Most instructors encourage the use of machines, calculators computers, phones etc., for analyzing data. The use of machines may be restricted during examinations or at certain other times. Ask your instructor for the policy in your class.

Students are not expected to be programmers or to know any particular computer language before starting this class. Instructors will expect students to be able to access information on the internet, for example MyMathLab, use calculators, and perhaps learn to use some other particular software with instruction. Basic skill in algebra and the use of mathematical symbols, order of operations etc., and the willingness to read and follow instruction manuals and help files will suffice.

Students' grades are based on homework, class participation, short tests, and scheduled examinations covering students' understanding of the topics covered in this course. The instructor determines the relative weights of these factors and the grading scale. See the syllabus for your particular class.

MAT 003 is a CR/NC class. You must earn 70% in the course to earn credit.

 10% of grade = Supplemental instruction 10% of grade = Assignments (class work, homework) 10% of grade = Quizzes 45% of grade = Exams (3 exams, 15% each) 25% of grade = Final Exam

### Location of Class Meetings

Classes meet on the dates and room announced in the official Schedule of Classes. This is a traditional, face-to-face class.

### Attendance Requirements

Attendance and participation are important to your success in this class. Students who skip classes generally fail. Ask your instructor for the attendance requirements in your particular class.

#### Supplemental Instruction (SI)

SI tutors will be available during class sessions to provide assistance for the students. SI tutors will conduct workshops on Fridays. Students are expected to attend the Friday workshops. During these sessions the SI tutor will review homework, give quizzes and prepare for upcoming lessons.

#### Creating Conditions for Successful Learning:

Research shows success in math class depends very much on two factors: the amount of time spent working on the material, and the student's beliefs about mathematics and what it means to understand and do mathematics. With this in mind, here are some suggestions:

• Be in class, every class, and be on time.
• Be prepared to participate in group work and discussions every day.
• Spend at least 1 hour every day, not including class time, working on homework assignments, and studying.
• Realize that success in mathematics is less about "ability" and more about willingness to think and to work hard to make sense of things.

### Policy on Due Dates, Make-Up Work, Missed Exams, and Extra-Credit Assignments

Assignments:Class work assignments are given in class and the discussion about them help you prepare for homework. We encourage you to work with your classmates to complete assignments. The homework will help you prepare for lecture, quizzes and exams. Due dates for online assignments are annouced online. Online assignments must be submitted by the due date for full credit, but they can be submitted at anytime for partial credit.

Quizzes: are drawn mostly from the homework. There will be no make ups for in-class quizzes or online review quizzes.

Exams: There will be 3 midterm exams, each worth 15% of your total grade. There will be no make-up exams. All exams are to be taken closed book, and closed notes. The final exam is cumulative and worth 25% of your grade.

Instructors may, or may not, choose to offer extra credit assignments. If extra credit assignments are offered they will be available to all students.

The mathematics department does not tolerate cheating. Students who have questions or concerns about academic integrity should ask their professors or the counselors in the Student Development Office, or refer to the University Catalog for more information. (Look in the index under "academic integrity".)

### Accomodations for Students with Disabilities

Cal State Dominguez Hills adheres to all applicable federal, state, and local laws, regulations, and guidelines with respect to providing reasonable accommodations for students with temporary and permanent disabilities. If you have a disability that may adversely affect your work in this class, I encourage you to register with Disabled Student Services (DSS) and to talk with me about how we best can help you. All disclosures of disabilities will be kept strictly confidential. Please note: you must register with DSS to arrange an no accommodation. For information call (310) 243-3660 or send an email message to dss@csudh.edu or visit the DSS website http://www4.csudh.edu/dss/contact-us/index or visit their office WH D-180

### Behavioral Expectations

The most important rule for this class is RESPECT THE RIGHTS OF YOUR FELLOW STUDENTS. Therefore, no disruptive behavior will be permitted during class time; this includes but is not limited to coming to class late, leaving early, use of cell phones or other communication devices (such as the ringing of phones or alarms). All cell phones must remain out of sight.
