Positive and Negative Integers: A Card Game This is an adaptation of the card game 25. You will need one standard deck of cards (jokers removed) per group of students (between 2 and 4 students per group). THE RULES • The dealer will deal out as many cards as possible from the deck, so that each person has an equal number of cards. • • Put aside any extra cards. Black cards represent positive numbers, Eg. A black seven is worth +7 (positive 7) • Red cards represents negative numbers. Eg. A red three is worth -3 (negative 3) - Aces have the value of 1 -Jacks the value of 11 - Queens the value of 12 -Kings the value of 13. • The player to the right of the dealer picks up a card and says it out loud. Eg. If the card is a black 8, the player says 8. • The game continues in a clockwise direction, with each player adding their card to the pile and saying the sum of the two cards out loud. Eg. If the next player picks up a red 9, it has a value of – 9. The player says 8+ (-9) = (-1). • The game continues until someone shows a card that, when added to the stack, results in a sum of exactly 25.
