Ever wonder why your cell phone charger gets so hot? Or how different devices plugged into the same charger take different amounts of time to charge?

Believe it or not, it has a lot to do with the constant of proportionality!

Use this artistic, real-life lesson plan to teach your students about the constant of proportionality and how to find k from graphs, equations, and tables. Students will learn material with artistic guided notes, practice and check for understanding with doodle math and a maze, and wrap up with the real life application of constant of proportionality for cell phone chargers.
