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
