 The game we are playing today is called Guess My Colors. We will use playing cards to take data from a sample to make inferences about a larger population. The materials you need to play this game include two decks of playing cards, Guess My Colors playing cards, and a notepad to keep score. Remove the jokers from the first deck of cards. From the second deck, remove the aces and kings and include these eight cards in the first deck. Now you have a deck with 60 cards, 30 of the cards are red and 30 of the cards are black. One player at a time has the deck. This person is the dealer. The others are called players. Players start with a set of three different Guess My Colors cards. Directions alternate between the dealer and the players. Dealer begin by removing 20 red cards or 20 black cards or 10 cards of each color. Put these off to the side face down without letting the other players see them. Flip four cards from the deck face up. Players decide whether or not you are ready to make a guess about which cards the dealer removed. If you choose to guess now, place the proper Guess My Colors card face down in front of you. Once you make a guess, it is final for the round. Dealer flip over four more cards. Players, you have another opportunity to guess here, but can choose to wait for one more round of four cards. Dealer flip over four more cards for a total of 12. Players, you must guess at this point if you have not already done so. Players, turn over your chose and guess my colors card to reveal your guess. Dealer, reveal the cards you've removed. 20 red cards, 20 black cards or 10 of each. Players are awarded points as follows. If you made a correct guess with four cards flipped up, you receive three points. If your guess was incorrect, you lose three points. If you guessed correctly with eight cards flipped up, you receive two points. If your guess was incorrect, you lose two points. If you waited to guess once 12 cards were flipped up, you receive one point for a correct guess. If your guess was incorrect, you lose one point. Follow-up conversations about how students thought about the data could benefit the whole group. Pause the video here to read our Think About It questions.
