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.
