REQUIRED TEXT: ESSENTIAL ARITHMETIC by Johnston, Willis and Lazaris, Seventh Edition.

COURSE DESCRIPTION: The purpose of this course is to enable students to become proficient in the manipulation and application of basic arithmetic skills. This is a variable unit class with a maximum of 5 units available. So, you get to decide how much you want to do this quarter! Each module is one unit and covers a different topic:

Math 181A Whole Numbers (Chapters 1 & 2)

Math 181B Fractions (Chapter 3)

Math 181C Decimals (Chapter 4)

Math 181D Percent and Ratio (Chapters 6 & 8)

Math 181E Introduction to Algebra (Chapters 11 and parts of 12 & 13)

It is strongly recommended that you complete all five modules before enrolling in either

Math 152A, Basic Algebra (Part I) or Bus 112, Business Math.

Students may use the time in class in the following ways:

a) Begin with a lecture and the rest of the class time will be to work individually getting assistance from the teachers as needed. Lectures will be presented following the time line beginning on page 4 of this syllabus. Students are encouraged to read in advance the material that is covered in each lecture. These students will meet in E106 with Jane.

b) You may work at your own pace requesting assistance as needed. These students will meet in A206 with Sheri or Christy.

You may move between the two groups as needed.

1) The odd problems from the Set I exercises for any section covered in the particular chapter.

2) All of the Set I exercises for each of the Review Sections (some chapters have more than one review).

3) The entire Diagnostic Test at the end of the chapter.

If a homework set is turned in incomplete, 10% will be deducted from the grade for each section that is not complete. This means that if three sections are not completed, then 30% will be deducted from the grade for that chapter.

Examinations are given at the end of each chapter. If the student does not receive a score of at least 70%, he or she will be asked to take another test after corrective action. If a student does need to take a second test, the highest score possible for that chapter is 70%.

• If there is one chapter in a module (modules B & C), the grade on the chapter test will be the grade in the module.
• If there are two chapters in a module (modules A, D & E), the average of the two chapter tests will be the grade for the module.
• EACH MODULE RECEIVES A SEPARATE GRADE. Grades are based on the following scale:

A 90% - 100%

B 80 - 89%

C 70 - 79%

D 60 - 69%

A student must obtain 70% or higher before he or she may proceed to the next module.

CALCULATOR: A calculator may be used in Module D.

LEARNING DISABLED STUDENTS: If you are in the Learning Disabled Program, please speak with Jane about your special needs. It is also important that one of us speak with anyone for whom math is extremely difficult.

1) Come to every class meeting.

2) Arrive early, get yourself settled and be ready when class starts. Sit where you won't be distracted.

3) Read each section before it is discussed in class.

4) Do all of the homework.

5) Do some math every day.

6) Start preparing for tests at least a week in advance.

7) Take advantage of tutors and office hours, extra help can make a big difference.

8) Do some review every time that you study math.
