B. COURSE DESCRIPTION
The course is an extension from elementary algebra with an emphasis on factoring, rational
expressions, graphing linear equations and inequalities, polynomial and rational functions, systems
of equations, rational exponents, radicals, and complex numbers. Intermediate algebra is a
preparatory course for college algebra.

C. METHOD OF INSTRUCTION
This will be a problem-solving oriented class. Lesson presentations may include chalkboard,
power point, and practice problems from the courseware. All homework must be completed in
one of the three methods discussed in class and unit tests will be given over the homework
assignments. It is the responsibility of the student to complete all homework assignments in order
to be ready for unit tests. Due dates for the homework will be listed on your progress report when
entering the software or the next class period if using the pencil/paper option. Practice tests can be
completed on the courseware.

D. COURSE OBJECTIVES
1. To help the student develop skills which will enable him or her to solve problems and
communicate effectively using the language and techniques of algebra.
2. To acquaint the student with some of the general concepts and principles of mathematics that
will
serve as a basis for further studies in mathematics.
3. To help the student build confidence in his or her ability to solve problems in mathematics.
4. To encourage the student to develop and use a sound mathematical vocabulary.
