This is a 30-slide PowerPoint deck to use as you play a game of Around the World with your students. This game will either allow students to learn through inference the rules of adding and multiplying variables or it will allow them to practice the rules that they have already learned. The questions switch randomly between adding and multiplying terms to help students compare and contrast adding and multiplying. The final slide gives students a chance to verbalize the rules they have learned by playing the game.
In my own classes, I have used this game as a refresher for upper-level math students before diving into deeper topics. It could also be used in a pre-algebra or Algebra I class to learn and practice the rules of adding and multiplying variables for the first time.
