Percent Composition, Empirical & Molecular Formulas Color-By-Number! Add art and creativity to your review lesson!
Students work ten problems, choose the correct answer, and color their masterpieces according to the color beside the correct answer. For early finishers, I let students “make it their own” by adding a background, and coloring parts of the drawing that don’t have numbers.
This is a great review assignment that will have students reviewing percent composition, empirical and molecular formulas in a whole-brain activity.
