Study Hall Games - posted September 4, 2000
Could you have guessed it? On the first day of school, my first class was a study hall! What did I do with a room full of eighth grade students and fifty-three minutes to fill?Never fear, I polled the students to find out which of the three games in my closet they might like to play. Then I created a math problem using the results of the poll.
Greg, John, Karla, Adam, and Allison said that they would enjoy playing all three games.
Stephen, Douglas, Erin, Katya, and Ashley said that they wouldn't play any of the games.
Eduardo, Michael, and Michaela wanted to play checkers and backgammon, but not chess.
Tyler and Jessica wanted to play backgammon and chess, but not checkers.
Parker would play chess and checkers, but not backgammon.
This gave me twenty-one students who would play backgammon or chess, twenty-four students who would play checkers or chess, and twenty-six students who would play checkers or backgammon.
How many students wanted to play only backgammon? Only checkers? Only chess? How many students were in my study hall?
Bonus: Since I only stock mathematical games in my closet, tell me something mathematically significant about each of the three games.
