        The Lowdown | Functional Relationships Between Quantities: Calculating Fuel Consumption

        In these interactive visualizations, explore the relationship between calculating miles per gallon (mpg) to gallons per mile in fuel use for vehicles. Most drivers think gas usage falls linearly (in a straight line) as mpg increases. But the actual relationship between the two is curved: one additional mpg has significantly greater impact in the gas consumption of an inefficient vehicle than it does in a more efficient vehicle. In the accompanying classroom activity, students will further explore this idea through guiding questions, classroom discussion, and a writing assignment. This resource is part of the Math at the Core: Middle School Collection.
