Student Outcomes

  • Students develop an intuitive understanding of equivalent ratios by using tape diagrams to explore possible quantities of each part when given the part-to-part ratio.  Students use tape diagrams to solve problems when the part-to-part ratio is given and the value of one of the quantities is given.
  • Students formalize a definition of equivalent ratios:  Two ratios, A:B  and C:D, are equivalent ratios if there is a positive number, c, such that C = cA and D = cB.
