# Day 67: Pirates of the Caribbean Visit an AP Stats Classroom

Today, as we are finishing up our study of Combining Random Variables, I decided to use an activity I found on Chuck Bakers website about Pirate Liar Dice. We first watched a clip from the Pirates of the Caribbean where the pirates are playing Pirate’s Dice, a game in which each player has 5 dice and a cup. Check out the clip:

Then my students talked about what happened during the game (some said they didn’t have a clue) but most were able to recall the progression of the bids: 4 fours, 4 fives, 5 fives, 8 fives, 12 fives. They still weren’t sure what was happening, so we then watch this “Liar’s Dice in 60 Second” to clarify the rules:

Finally, they played. I don’t have enough dice for each student to get 5, so we used our Nspires and the randint( command to simulate rolling 5 dice. Then the bidding became. They had fun for sure and there were some subtle probability ideas percolating.

Our debrief after the game included the following questions:

- What were some things you thought of as you made bids?
- How did you know how many dice were left in play?
- How did you keep track of what dice the other players may have had?
- How improbable did a bid have to be for you to challenge it?
- When was it easier to make a safe bid?
- When was it harder to make a safe bid?

One of our vice-principals (who taught AP Stats in a former life) happened to be walking by so he popped in and joined in the discussions. Fun times for all, and hopefully a memorable experience for my students.
