At the end of this lesson, student will be able to:

• Interpret complicated expressions (absolute value) by viewing one or more of their parts as a single entity. ACOS 6b
• Create absolute value equations and/or inequalities in one variable and use to solve problems. ACOS 16
• Represent constraints by inequalitites and interpret solutions of inequalities as viable or nonviable options in a modeling context. ACOS 18
• Show how extraneous solutions arise with absolute value ACOS 20
