So today I created a small little package to be added to the homework zone bin…
A Deck of Cards!
And for that deck of cards, here is a small collection of math-oriented, competitive card games:
Game 1: “Racing Stripe”
This game is a head to head racing competition. Divide the pack as you wish (Each player can have 5 cards or 25! It’s up to you). With your cards, race to place your cards in order from least to greatest. Fastest player wins the race!
(Added challenge: Make one colour – either black or red – negative numbers!)
Game 2: “Battle”
This is also a head-to-head competition. Divide the deck in two and give each player a pile. Do not peek at your cards! Each round, players flip a card. The higher card wins the set. The player with the most cards at the end wins.
Game 3: “Fraction Battle”
This game has the same rules as “battle”, but with a more complicated twist! Each turn, players will draw 2 cards. The first card will be the numerator, the second card will be the denominator. The player with the larger fraction will win all 4 cards!
Game 4: “Multiplication Battle”
This game also has the same rules as the two prior battle games. For this, players flip 2 cards. The player with the greatest product will win all 4 cards.
Game 5: “21”
This game is a classic! This game is best for 2-4 players, but one player needs to be the dealer. The goal of the game is to have your cards total as close to 21 as possible WITHOUT going over. Each player is given 1 card. When it is their turn, they can either ask the dealer for another card or they can “hold” (which means they have chosen to not take any more cards at all). Players can ask the dealer for an extra card each turn if they choose. The moment they say hold, they cannot ask for anymore.
As players gain cards, they must add the numbers. If a player totals over 21 at some point, they are out of the game. Once all players have chosen to hold OR there is only 1 player left, the game ends. The player with the total closest to 21 without going over wins.
Game 6: “Give me ten”
Remove face cards from the deck. Ace is left as equals 1. Arrange the cards face up in a line. Players take turns grabbing cards that, combined, total 10. When all the cards are gone, the player with the most cards wins. (Hint: Go for multiple card combinations first, like 3+3+4).
[Challenge: Make one colour – either black or red – negative integers]
Game 7: “Mind Reader”
This game is best for 3 players. Two players each draw a card and, without looking at it, hold it up to their foreheads so that everyone else can see it, but themselves. The third player announces the sum of the two cards. Each “mind reader” must figure out which card is on his or her own forehead and say it aloud. When both “mind readers” have figured out their cards, a new leader is chosen and the game continues.
[Challenge: Have the third player announce the product of the two cards]
Game 8: “Subtraction Toss Up”
Game best for 2-5 players. Each player chooses 3 cards from the deck without looking at them. Players then toss their cards in the air. Once the cards land, see which landed face up and which landed face down. Total the sum of the card(s) facing up, then subtract the value of the card(s) facing down.
Goal 1: Play to the end of the deck. Once the deck is finished, the player with the greatest total wins.
Goal 2: Continually use the cards and resort the deck as you play. First player to reach 100 wins.
