Basic Mathematical Skills with Geometry, 9th edition, by Barrato & Bergman

Prerequisite: None 

Credit: Not degree applicable

Course Description:

This introductory arithmetic course is designed to develop number and operation sense using whole numbers, fractions, decimals, and percents, as well as develop problem-solving skills. Topics include writing whole numbers and decimals in various forms, estimation, ratios, proportions, and applications.

Note: Students enrolled in this course are required to participate in individual and group activities.

Course Objectives and Methods of Evaluation:

Course Objectives:

  1. Read and write whole numbers and decimal numbers in standard, expanded, and written form.

  2. Order a given set of numbers.

  3. Use the order of operations to add, subtract, multiply and exponentiate whole numbers, fractions and decimals.

  4. Use rounding techniques to estimate results of operations on whole numbers, fractions and decimals.

  5. Use divisibility tests and prime factorization to reduce fractions to lowest terms and perform operations on fractions.

  6. Convert rational numbers into decimals, fractions and percentages.

  7. Solve various application problems requiring the use of ratios, proportions, and percentages.  

SLO Statements:


SLO #1 Application Problems: Students will be able to recognize addition, subtraction, multiplication, division, exponentiation, factoring and order of operations in a given context (word problem, data, diagram, etc.) involving non-negative real numbers  to write corresponding mathematical expressions and solve authentic, real-world application problems.

SLO #2 Solving Equations and Manipulating Expressions: Students will be able to use numerical and symbolic representations to correctly perform operations (addition, subtraction, multiplication, division, exponentiation, factoring, and order of operations) on non-negative real numbers to simplify expressions.

SLO #3 Visual and Graphical Methods: A student completing Pre-Collegiate mathematics will use visual and graphical methods to represent and analyze information and to solve problems using non negative real numbers, including demonstrating correct ordering of values and testing reasonableness of solutions.

SLO #4 Articulating Mathematical Reasoning: A student completing Pre collegiate mathematics will verbally articulate (orally or in written form) the mathematical reasoning they used to solve a problem or analyze a situation.

Methods of Evaluation:


Student with THREE consecutive absences MAY be dropped from the class! Any student who misses two exams will be dropped from the class. Excessive absent will be dropped. 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!

NO Calculators allowed.


Success in any math class is dependent upon completing and understanding all assignments. 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 10 in class pop quizzes and no make-ups allowed.


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 five 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.

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 310-660-3295 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 Wonderful Spring 2015!
