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.
