REQUIRED TEXT:             Basic College Mathematics, by Tobey & Slater, Sixth Edition.

 

COUSE DESCRIPTION:    The purpose of this course is to teach students the skills of basic arithmetic.  In reality, you have probably already seen this material somewhere in your educational past but may have forgotten it or never really understood it when it was first presented.  In this class, our goal is to fill in the gaps of your knowledge about arithmetic and to help you get the “big picture” so that it will all fit together in a way which makes sense to you and that you are able to apply it to “real life” problems.  Calculators are NOT allowed in this class!

 

                                                This is actually two six-week classes (each receiving its own grade):

Ψ      Math 191AL covers whole numbers, fractions, and an introduction to decimals.

Ψ      Math 187B covers the rest of decimals, percents, and an introduction to algebra.

 

STUDENT OUTCOMES:    The successful student in Mat 187B will be able to:
1. Solve problems involving decimals, percents and beginning algebra.
2. Translate written statements in to mathematical statements.
3. Apply the topics of Basic Arithmetic (Part II) to real life situations.

 

GRADING POLICY:           Method of Student Evaluation, MAT 187B

                                                Homework (22 sections at 5 points each)                      110 points

                                                Exams* (Two at 100 points each)                                 200 points

                                                Final (Covers entire course content)                              140 points    

 

Your letter grade will be based on your percentage of the 450 possible points for MAT187B.

                                                            A         90-100%         

                                                            B         80-89%

EXAM POLICY:                  Grading will be based on progress towards the final answer, and the demonstration of understanding of the concept that is being tested. The more you show me with steps and detail, the better your chances for partial credit.  You provide me the communication and detail in your answers; and I will give you the best grade I can based on that communication and answer. You can use one page of notes, front and back, for chapter exams and final, but not for quizzes.

 

MAKE-UP POLICY:            For Chapter Exams and Final, make-up is possible, but there is a 10% penalty if the absence is not excused. The make-up test needs to be taken before the next class. The absence is excused for medical emergencies with the doctor’s note. You can take your test early if you know you are going to miss the class.

For Homework, you must show your work to get credit, half credit for completion and half credit for selected problems. Homework will be accepted late up to one week after it is assigned for half credit. You can turn in your homework early if you know you are going to miss the class. You can consult a classmate, a tutor, your instructor, or anyone for assistance on the homework.

 

COMMUNICATION           You can communicate with me either by coming to class or office hours, sending

POLICY:                                an e-mail, or calling on the phone. I will respond to your e-mails in a timely

                                                manner, and I will do my best to return your calls (you need to make sure to leave your number clearly). If you miss the class, it is your responsibility to pick up the class handouts or obtain the information either from your classmates or from me during the office hours.

 

I have students work together to help each other. Please feel free to ask me directly if you like to work with me one-on-one.

 

·   Please come see me if you do not understand my policies.

·   Due to English is my secondary language, please be sure to ask me if you have any difficulty to understand math due to my accent, and I will clarify.

 

CALCULATORS:                Calculators are not allowed in this class.

 

LEARNING                           If you have a certifiable learning disability that may affect your performance in

DISABILITIES:                    this class, be sure to discuss your special needs with me during the first week of class.  Learning disabilities will be accommodated.

 

REGISTRATION:                ·   You must register for this class at the Office of Admissions and Records.

·    It is your responsibility to drop the class in order to avoid an unwanted grade. You can choose Credit/Non-Credit for the class before the date specified on the schedule. I will drop a student from the class if the student misses more than two classes and is unable to keep up with the leaning.

Tentative Lecture Schedule for Math 187B

 

Be sure to use class time, office hours, and the MSC to get all of your questions answered.

For your homework, make sure you separate each section on the different pages and separate each problem on the different lines. There will be one point deduction for each section if the grader cannot read your answers. ALWAYS WRITE THE HOMEWORK # AND SECTION #s FOR EACH HOMEWORK; MAKE SURE TO WRITE THE DATE THAT YOU TURN IN IF YOU TURN IN HOMEWORK LATE.

 

NOTE: 1. Make sure you count the problem numbers correctly. Don’t do the wrong numbers.

             2. Don’t copy the questions for the word problems.

 

EOO means Every Other Odd (i.e. #1, 5, 9, 13,...)
