Learning Objectives•Understand the Properties of Inequalities•Be able to Solve One-Step & Multi-Step Inequalities•Understand and be able to Write Set Builder Notation•Be able to convert a Written or Literal Statement to an Algebraic Inequality•Understand Compound “AND”/”OR” Inequalities and be able to Graph them and Write them using “Intersect” & “Union” Symbols•Be able to Solve Compound Inequalities•Be able to Absolute Value Inequalities•Be able to convert a Written or Literal Statement to an Algebraic Inequality

Inequalities•Inequalities are Relationships where the comparison is “not” an “Equal” comparison.•One side of the comparison is either “Less-Than”, “Greater-Than”, “Less-Than or Equal-To”, or “Greater-Than or Equal-To”•The Inequality Symbols are: < , >, ≤, ≥•The “Closed End” of the symbol always faces the side of the comparison with the smaller amount while the “Opened End” always faces the side of the comparison with the larger amount

Presenting Inequality Solutions(Number Lines)•Inequality Solutions should first be presented on a Number Line to stimulate and engage the Visual Senses.•All numbers represented in the Solution should be part of a thickened Line Segment or thickened Arrows•The starting or ending points of thickened Line Segments or Arrows should be represented by a “Filled Dot” or an “Unfilled Dot” depending on whether the end point is “Included” or “Not-Included” respectively. (One end of Arrows is an arrowhead which must always be at “Infinity” or “Negative Infinity” and is never included.

Presenting Inequality Solutions(Interval Notation)•Inequality Solutions are Intervals as opposed to Discrete or Individual values. The Solution has a starting value, an ending value, and includes every possible real number in between.
