This course provides a conceptual study of problems involving linear expressions, equations, and inequalities. Emphasis is placed on solving contextual application problems. Upon completion, students should be able to distinguish between simplifying expressions and solving equations and apply this knowledge to problems involving linear expressions, equations, and inequalities.

·Differentiate between expressions, equations, and inequalities
·Simplify and evaluate, when appropriate, expressions, equations, and inequalities
·Effectively apply algebraic properties of equality
·Correctly represent the solution to an inequality on the number line
·Represent the structure of application problems pictorially and algebraically
·Apply effective problem solving strategies to contextual application problems
·Demonstrate conceptual knowledge by modeling and solving applications using linear equations and inequalities
Student Learning Outcomes
4.1 Demonstrate the use of a problem solving strategy to include multiple representations of the situation, organization of the information, and algebraic representation of linear equations or inequalities
4.2 Represent verbal statements as algebraic expressions, equations, and inequalities
4.3 Distinguish between problem events that use expressions, equations, or inequalities
4.4 Solve linear equations and inequalities in one variable using algebraic properties of equality
4.5 Demonstrate an understanding of the meaning of solutions to problems, i.e. identity, contradiction, conditional
4.6 Represent solutions of inequalities on a number line
