Sample Learning Goals

  • Interpret ratios of mixed units (e.g. $/lb)
  • Define the unit rate and determine a method to calculate it
  • Predict how changing the numerator or denominator of a rate will affect the unit rate
  • Use the double number line to reason about rates and solve real-world problems
  • Develop strategies to use the unit rate to solve problems
  • Compare unit rates between two simultaneous situations
