Ask students what the probability is that the upside down card will cause you to bust, cause you to reach 21, and cause you to reach a number lower than 21. Based on these probabilities, vote on whether to hit or stay. Turn the card over to reveal a 7. Divide students into pairs, each with a deck of cards. In each pair, one student is the dealer and the other is the gambler for blackjack.
Groups then share their data with the other groups.
Create a graph depicting one of these trends and write a short analysis explaining possible reasons for this trend and addressing the possible psychological factors behind it. Students will be evaluated on participation in class discussion, participation in partner experiments, and completion of graphs and analyses of trends from the class data. Create a chart all the way up to ten dice. Ask each person to choose a number, explaining that the winning number will be the one that comes closest to the sum of all of the numbers chosen, divided by two. After everyone has chosen, and the winning number is revealed, ask the students why they chose their number.
