Texas Instruments: Numb3 Rs: Barging In

Based off of the hit television show NUMB3RS, this lesson exposes students to equations of variation (direct, inverse, and joint) in the real world, as well as having students work with such equations in the real world context. The lesson is framed in the context of a barge which had a certain amount of fuel before setting off on a short voyage, and students are to determine how far the barge has gone based on the amount of fuel in the hull. Students will write their own equation of variation for the lesson.
