Essential Knowledge and Skills 
  • Demonstrate absolute value using a number line.
  • Determine the absolute value of a rational number.
  • Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle to solve practical problems.† Revised March 2011
Essential Understandings
  • Why is the absolute value of a number positive? The absolute value of a number represents distance from zero on a number line regardless of direction. Distance is positive.
