Texas Hold-em The Algebra Lab Way

How to play Each group of 2 will get 2 cards (face-down) Dealer will deal (face-up) cards for the groups to choose from. An algebra problem will be presented to the class. Once you and your partner think you have the right answer, bring it (paper ONLY) to Mrs. T to check. If the answer is correct, you may choose a card to add to your hand. If your answer is incorrect, return to your group and try again. Repeat for Rounds 2 and 3. Round 4 will be played so that the groups can “trade-in” a card to try to better their hand. Winner is determined by the best poker hand at the end of 4 rounds.
