Math Circle on Wed Feb 8

Today we played a new game called the Game of Nim.

We started out by playing a one stack version of the game.  In Nim, you have a stack of chips and can take 1, 2 or 3 chips away from the stack.  The player who ends the game with a chip loses.

I had the students develop strategies for winning this game.  They realized that if you had 4 chips in front of you, you were guaranteed to win. They realized that it was a goal to try and get to that 4 chip stage, so they came up with plans for what to do if you have 6, 7 or 8 chips in front of you.

We then played a two stack version of the game.

Please feel free to play Nim at home with your child.  It is a lot of fun.
