A "Sticky" Situation
|
Copy onto cards the expressions listed below. One group member shuffles the cards and deals three cards to each of the other two.
The group members with cards first must use a pattern to estimate the quotient or product of each expression on the cards in their hands. Then each player must find the sum of these estimates to get the total for the hand. The winner is the player whose hand comes closest to 21,000 without going over. Players may choose to stick with the cards they have or to receive an additional card from the dealer. There is no limit to the number of additional cards that may be received, but once a player "sticks," additional cards are not allowed. After three hands have been played, trade roles. Each group member should deal at least three hands.
