I use these cards for math centers and small group math lesson activities. I mainly use them to play "Ten Frame War" and a basic matching game. I use this with my first graders but you could easily use the game with kindergarten and second graders as well! You may print several copies, I usually print 2 sheets of the number and ten frame cards per game. I have found that the eight 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!
For the matching game they just simply match the number to its ten frame equivalent.
