 ### Algebra I

Course Outline/Objectives

The key content for the Algebra I, involves understanding, writing, solving, and graphing linear and quadratic equations, including systems of two linear equations in two unknowns. Students should also become comfortable with operations on monomial and polynomial expressions. They learn to solve problems employing all of these techniques, and they extend their mathematical reasoning in many important ways, including justifying steps in an algebraic procedure and checking. The main topical objectives are:

Brief Course Description

Symbolic reasoning and calculations with symbols are central in algebra. Through the study of algebra, a student develops an understanding of the symbolic language of mathematics and the sciences. In addition, algebraic skills and concepts are developed and used in a wide variety of problem-solving situations. Through practice and applications, students develop skills in dealing with the essentials of a first-year algebra course, including properties of and operation with real numbers, linear and quadratic equations, inequalities, polynomials, rational expressions, radicals, problem solving, factoring, and graphing.
