Problem Based Learning - This activity connects solving systems of equations to the real world! What if nutrition labels told you how long you needed to exercise to burn off the calories for that product? Would it make you think twice before consuming the extra bag of chips or soda? Through this activity, students create systems of equations to model real world situations involving exercise and calories. A lesson plan as well as an answer key is included. The activity is set up as a menu to give students choice in which questions they would like to solve. As an extension, they can get creative and design their own nutrition label.
