Need to teach the difference between Theoretical and Experimental Probability or introduce the Law of Large Numbers? Students will have fun and compete while thinking mathematically about a game they know, exploring principles of probability, learning new vocabulary, and converting between fractions, decimals and percents.
This activity is highly structured and organized, works well for a 1-hour class period and provides great notes to refer back to before a test. It is step by step, and students will stay engaged throughout the lesson. It can be easily differentiated or edited as needed! You won't need an answer key for this one since the students will generate all of their own data during the class.
Before introducing the activity, allow students to get into pairs. This particular activity is a great opportunity to pair students with different math ability levels. You can introduce the game of rock, paper, scissors any way you like, but it's a lot of fun to end the class or provide an extension by exploring the possibility that rock, paper, scissors might not just be about chance. There are plenty of online resources out there to see what research and experience has to say. Have fun with this activity (and enjoy watching your students have fun with it too!).
