The Spinner Game   Purpose: Introduce the concept of probability and the idea of a fair game.     In class we partnered up played a game that involved 2 circle­shaped spinners.   ● Both are divided e ​ qually i​ nto three parts with a number on each space.  ● Each player used a paper clip as a spinner. We used a pen/pencil and  placed its point end in the loop of the paperclip.   ● The partners were to spin their spinners at the same time. The player that  would spin the h ​ ighest number was the winner.   ➔ Note: the numeral in Spinner A is 9.                                  Spinner A                                                Spinner B  First before playing the game, the teacher asked the class if we thought the  game was a fair game. Out of 13 students, 6 of us thought the game was  fair.  The class played 20 rounds.    Question: Do you think it is a fair game? Explain.      Remember, 6 out of 13 students thought the game was fair. Therefore the  probability of students thinking it was a fair game would be 6/13, written as  Probability (Fair): 6/13  `````````````````````````````````````````````````````````````````````````````````````````````````````  There were a total of 7 groups. Here are the results of the winners.     Spinner A: 1 Spinner B: 4  Tie: 2        The probability that Spinner A won: P ​ (A): 1/7  The probability that Spinner B won: P ​ (B): 4/7  The probability that there was a tie: P ​ (Tie): 2/7    Since there were 7 groups the denominator is 7. If you add up the three  probabilities, the the total will be 7/7, or 1.
