Prerequisite: Math 10B or Math 12 with a minimum grade of C in prerequisite or qualification by testing (ECC Math Placement Test) and assessment.

Course Description: This course bridges the gap between arithmetic and formal algebra, developing number sense and operation sense, in order to formulate and solve algebraic equations with integers, fractions, and percent. Algebraic principles are applied to problems from a variety of fields. Other topics include: proportional reasoning, spatial reasoning, informal geometry and measurement, coordinate graphing, informational graphs, and data collection and description.



Course Objectives and Methods of Evaluation:

Course Objectives:

  1. Acquire effective study skills including the use of the calculator in appropriate situations.
  2. Perform various operations (addition, subtraction, multiplication, division, and exponentiation) on different sets of numbers (whole, integer, and rational) and recognize equivalence when it occurs, particularly with fractions, decimals, and percent.
  3. Formulate mathematical representations of real-world applications including the recognition of proportional relationships.
  4. Estimate to determine the reasonableness of results.
  5. Recognize and apply the concepts of variable, expression, and equation.
  6. Solve linear equations.
  7. Find perimeters, areas, and volumes of various geometrical shapes and use in applications.
  8. Represent linear relationships with tables, graphs, and equations (coordinate graphing).
  9. Read, interpret, and construct tables, charts, and graph

SLO Statements: 

SLO #1 Application Problems- Students will recognize the underlying mathematical concepts in order to successfully evaluate expressions and formulas in a given context (word problems, data, diagrams, etc.) and apply those concepts correctly in authentic, real-world application problems.

SLO #2 Solving Equations and Manipulating Expressions- Students will use numerical and symbolic representations of mathematical ideas to simplify linear expressions and solve linear equations.

SLO #3 Visual and Graphical Methods- Students will be able to use visual or graphical methods to solve linear equations and problems involving geometry and measurement.

SLO #4 Articulating Mathematical Reasoning- Students will verbally articulate (orally or in written form) the mathematical reasoning they used to solve a numeric or linear problem or analyze a numeric or linear situation.


Methods of Evaluation:


Students with THREE consecutive absences MAY be dropped from the class! Any student who misses two exams will be dropped from the class. Students are responsible for any material/announcements missed in class regardless of their presence including being aware of your status in the class. You are expected to be present on time at all class meetings and to actively participate! You are expected to be at all class meetings on time!! Taken this class seriously is the first step to your success. Students will not be permitted to attend classes in which they are not enrolled.


Withdrawal from the class through the Admissions Office is the student's responsibility. If you have any concerns regarding your attendance, please contact me immediately via email, telephone or during my office hours. 

Academic Integrity:

Students are responsible to inform themselves of College policies regarding the Code of Academic Integrity incident of cheating will be brought to the immediate attention of the Academic dean and appropriate actions will be taken including receiving an F grade for the course. A report will be filed with the Campus Disciplinarian. CHEATING WILL NOT BE TOLERATED!



Scientific Calculator is allow. No cell phones use will be allowed in class! Cell phones must be completely off otherwise you will be asked to leave the class and one absence will be granted to you. Cell phones may not be used as calculators!!



Success in any math class is dependent upon completing and understanding all assignments. Most homework will be given on-line. The work you need to do to complete your on-line homework should be neatly written in your notebook together with the title, section and the grade you earn. Absolutely no late homework will be accepted! It is the student's responsibility to obtain the assignment during an absence. 

Class work:
You will often be given class work and it may be collected at any time during class. No makeup work is possible for missed class work. 

There will be in class quizzes. There are no make-ups on quizzes.



All homework will be done in a notebook neatly and organized by the chapter and section title. It will be collected on the day of the exam.



There will be four exams and a comprehensive final at the end of the 16 weeks semester. No make-up exams will be given but your final exam will only replace one missed exam. Contact me immediately if you miss an exam. Students who miss more than one exam will be dropped from the class. Tentative exam dates are noted on the Class Schedule at the end of this syllabus.


For online assistance with this course 24/7 you can log in to WebAssign.

“Developed by professors based upon their classroom experiences, WebAssign is designed to provide a convenient and engaging way for students to solve math problems and/or submit online homework while receiving immediate feedback and tutorial help.  The math exercises are tied to resources from the textbook – including video, interactive tutorials, and pages of the text – which maximizes the student’s efficiency while studying.  WebAssign is available at all hours of the day, through a variety of web browsers and operating systems.”

Students with Special Needs ADA:
Students with disabilities who believe they may need accommodations in this course are encouraged to contact the Special Resource Center at 310-900-1600 Ext# 2405 at Vocational technology Bldg. Room# 226B as soon as possible to better ensure such accommodations are implemented in a timely fashion. As well, please contact me privately to discuss your specific needs.



Keys to success:
It is expected that students spend a minimum of at least TWO hours outside of class for each hour spent in class. Spending more time on material from class and explaining concepts to other students in class is an excellent way of achieving success. Active participation is very important. Ask questions, answer questions, talk to other students in class, form study groups outside of class, and always remember to ponder beyond what we discuss in class! Next, remember to keep an open mind. A big part of learning and understanding mathematics is believing that you are capable of succeeding. Always remember to have fun!!

Students will be assessed through class participation, their performance on exams, quizzes, and assignments. The completion of the assignments will prepare you for each quiz/exam. You are expected to complete each assignment by the next class meeting so that you are ready to ask questions in class. You should see me for assistance as soon as an exercise is not understood, but not without first seriously attempting to do the problem on your own. It is highly recommended that you also take advantage of the various tutoring services offered on campus. It is your own responsibility to have an interest in your education.


I look forward to a Wonderful Fall 2015!
