My husband and I often play Rock Paper Scissors in order to determine who will take the dogs out, or who will let the chickens out in the morning, or who will have to do a dreaded chore of some kind around the house. I’m not sure how it all started, but it seems like we play that game at least every other day. I remember hearing a radio report–awhile back–about a study related to Rock Paper Scissors, and it was reported that Rock was the most popular among the three possible moves in the game. Thus, you might begin the game with Paper if you think your opponent will choose Rock. However, your opponent might think you are going to choose Rock and begin with Paper, so you are really better off, because of that, choosing Scissors.
Hearing about that study got me thinking about whether I might be able to design some kind of classroom activity around Rock Paper Scissors. I’m not sure what it would look like or where exactly it would fit into the curriculum, but it makes me smile to think of a classroom full of students playing Rock Paper Scissors.
Did you know there is a society–the World RPS Society–devoted to Rock Paper Scissors? They even have national championships! They share many interesting strategies on their website about how to beat others at Rock Paper Scissors.

I especially like the following information that is shared on the site:
“Contrary to what you might think RPS is not simply a game of luck or chance. While it is true that from a mathematical perspective the ‘optimum’ strategy is to play randomly, it still is not a winning strategy for two reasons. First, ‘optimum’ in this case means you should win, lose and draw an equal number of times (hardly a winning strategy over the long term). Second, Humans, try as they might, are terrible at trying to be random, in fact often humans in trying to approximate randomness become quite predictable. So knowing that there is always something motivating your opponent’s actions, there are a couple of tricks and techniques that you can use to tip the balance in your favour.”
The site goes on to add that males have a tendency to lead with Rock on their opening throw. Of course, I knew that. How do you think I’m able to beat Chad so often?
