Student Outcomes

  • Students justify the distance formula for rational numbers on a number line:  If p and q are rational numbers on a number line, then the distance between p and q is |p – q|.
  • Students know the definition of subtraction in terms of addition (i.e., a – b = c means that b + c = a) and use the definition of subtraction to justify the distance formula.
  • Students solve word problems involving changes in distance or temperature.
