Student Outcomes

  • Students understand that two quantities are proportional to each other when there exists a constant (number) such that each measure in the first quantity multiplied by this constant gives the corresponding measure in the second quantity.
  • When students identify the measures in the first quantity with x and the measures in the second quantity with y, they will recognize that the second quantity is proportional to the first quantity if y=kx for some positive number k.  They apply this same relationship when using variable choices other than x and y.
