Fair and Unfair Games Laura Smiley

What makes a game… FairUnfair

FAIR GAMES  A fair game gives every player the same chance to win. Example of a fair game: o Toss one penny. If the penny lands heads up, Player 1 wins. If the penny lands tails up, Player 2 wins. o There are two outcomes: heads and tails. Each player has the same chance to win.

UNFAIR GAMES Example of an unfair game: o Toss one penny. If the penny lands heads up, Player 1 wins. If the penny lands tails up, Player 2 loses. o There are two outcomes: heads and tails. Player 1 wins either way.  An unfair game does not give every player the some chance to win.

Player A wins if 1, 3, or 5 is rolled. Player B wins if 2, 4, or 6 is rolled. Player A wins if numbers < 4 are rolled. Player B wins if numbers > 4 are rolled. Player A wins if prime numbers are rolled. Player B wins if non prime numbers are rolled. Player A wins if 4, 5, or 6 is rolled. Player B wins if 1, 2, or 3 is rolled.

Can you make a fair game that has three players with this spinner?

Can you make a fair game with this spinner with 3 players? 4 players?

PROBABILITY GAMES In your groups, you will create a probability game. Use what you have learned about probability, ratios, and outcomes. Your game must have the following parts: It must be about something we have learned. It must be a game a group of students can play. It must be original. You may use any of the provided supplies. You will also need to present it to the class. In your presentation, you will share with us what it is about, how you play it and it’s name. We will record the presentation with a flip camera.
