Focus: Variable Equations and Properties
The student will graph inequalities on a number line. 


Essential Knowledge and Skills 
 Given a simple inequality with integers, graph the relationship on a number line.
 Given the graph of a simple inequality with integers, represent the inequality two different ways using symbols (<, >, <, >).

Essential Understandings 
 In an inequality, does the order of the elements matter? Yes, the order does matter. For example, x > 5 is not the same relationship as 5 > x. However, x > 5 is the same relationship as 5 < x.
