Anything with the title “War” gets a thumbs up with my boys.  War, a common card game, has a lot of mathematic potential!

War card game

The Basics of War

Supplies:  Standard deck of playing cards with 52 cards

Number of Players:  Two

Length of Time:  15-45 minutes (depending on level)

Goal:  To win all of the cards

Basic rules:

  1. Shuffle the deck of cards.
  2. Deal the cards so that each player has 26 cards.  Players keep their cards in front of them, face down.
  3. Each player simultaneously flips over their top card.  The player with the highest card wins both cards.
  4. If the players have the same card (a tie), there is a war.
    1. Each player places three cards in front of them, face down.
    2. Flip over a fourth card.
    3. The player with the highest card wins every card (all ten cards in the middle of the table.)
  5. The first person to win all of the cards wins the game.

 

 

Preschool or Kindgergarten…..recognize and compare numbers 2-10

Preschool/Kindergarten Math

Goal:  To help the child recognize and compare numbers 2-10

  1. Remove all of the face cards, jokers, and aces so that the deck only contains numbers 2-10.
  2. Play the game as described above, but with less cards.
  3. As you play, ask these questions:
    1. What number do you have?
    2. What number do I have?
    3. Which number is greater….is more?
    4. Which number is smaller….is less?
  4. If necessary, provide a manipulative to help the child decide which number is greater.
    1. Place two bears next to the two playing card and place five bears next to the five playing card.
    2. Which card has more bears?

 

Lower Elementary…..Practice Addition or Multiplication Facts

Lower Elementary Math Game

Goal:  To help the child practice addition and multiplication math facts.

  1. Remove all of the face cards, jokers, and aces so that the deck only contains numbers 2-10.
  2. Play the game as described above, except each player will draw two cards from the top of the deck.
  3. If practicing addition facts, the player will add the two numbers on the cards.
  4. If practicing multiplication facts, the player will multiply the two numbers on the cards.
  5. The person with the highest sum or product wins all four cards.
  6. If necessary, use manipulatives to illustrate the math problems.
    1. “My first factor is five, so I will get five cubes.  My second factor is two, so that is telling me that I will have two groups of five cubes.  How many cubes do I have altogether?”

 

Upper Elementary….Practice using multiple operations with three numbers….addition, subtraction, multiplication, division, squares, or cubes.

Upper Elementary Math Game

  1. Remove all of the face cards, jokers, and aces so that the deck only contains numbers 2-10.
  2. Play the game as described above, except that each player will draw three cards from the top of the deck.
  3. Each player may use any operation necessary to create the highest number possible with the three cards.  The numbers can be in any order.  All numbers must be used.
  4. If my three cards are five, two, and six…..I could create the following sums:
    1. 5+2+6=13
    2. 5-2+6=9
    3. 5×2+6=16
    4. 5x2x6=60
    5. 6/2+5=8
    6. 5 (2+6)= 40
    7. More complex………6squared + 5squared+ 2 squared=65
    8. Even more complex……..6cubed+5cubed+2cubed=349
    9. any operation, any combination!
  5. The player that creates the highest number wins all six cards.
  6. Variations: The player that creates the lowest number wins all six cards.
