This is a game I use with my first graders. I use it in math centers and small groups. You could easily use the game with kindergarten and second graders as well! You may print several copies, I usually print 5 sheets per game. I have found that the five sheets are good for up to 4 or 5 players.
I'm sure most of you know how to play war, I will include a brief explanation for those unsure how to play.
To play you simply pass out all the cards evenly to all players. (Simply set aside any cards that are left over.) Each player places their cards with the graphic side facing up in front of them. then all players flip their top card over and the player with the highest number wins all the cards that were played that hand. The winner places the cards in their "win pile". You do this until all the cards have been played. The player with the most cards at the end wins the game!
