Standards & Objectives

Learning objectives: 

Students will:

  • Given size and price of a shoe, graph price vs. size on a coordinate plane
  • Given size and weight of a shoe, graph weight vs. size on a coordinate plane
  • Calculate unit rate ($/oz) for different sizes of shoes, and describe how unit rate changes as size changes
  • For a given cost per ounce (e.g. $5.75/oz), calculate how much each size would cost if Nike charged by weight
  • Discuss advantages and disadvantages of this alternate pricing scheme
