Student Outcomes

  • Students understand that an inequality is a statement that one expression is less than (or equal to) or greater than (or equal to) another expression, such as 2x + 3 < 5 or 3x + 50 ≥ 100.
  • Students interpret a solution to an inequality as a number that makes the inequality true when substituted for the variable.
  • Students convert arithmetic inequalities into a new inequality with variables (e.g., 2 x 6 + 3 > 12 to 2m + 3 > 12 and give a solution; for example, m = 6, to the new inequality.  They check to see if different values of the variable make an inequality true or false.
