Adding War



Grades 1 - 3


  • addition facts 1 to 10
  • 1 to 18 combinations


  • 2


  • Grades 1 - 2: playing cards Ace (= 1) through 5 (making sums to 10)
  • Grades 2 - 3: playing cards Ace (= 1) through 9 (making sums to 18)


Players divide the cards in the deck evenly between themselves. Each player turns over two cards and adds them together. The highest sum gets all of the cards.

In the event of a tie (if each player has the same sum), war is declared. Each player deals out three more cards face down. Then each player turns over two more cards and adds the sum of the numbers on those cards to the original sum. The highest sum wins all of the cards.

Play continues until one player has collected all of the cards.

Joanne Currah and Jane Felling have created two best-selling math game books -- Shuffling Into Math (for teachers of grades K-3) and All Hands on Deck (grades 1-9). Each book includes simple instructions for more than 100 math games that help children discover math concepts and reinforce math skills. Education World is pleased to present a selection of those activities in this series.
