Teachers, save “Rounding War” to assign it to your class.

You'll need regular playing cards with the face cards removed for this game. Split the deck into two piles (one for each player). Each player will turn over 3 cards to make a 3-digit number. Each student rounds their number to the nearest hundred. Whoever has the biggest rounded number wins- just like in the War card game. You may rearrange your cards to make the biggest rounded number you can. (If there is a tie, play again.) The winner takes all of the cards for that round and they keep playing. The player with the most cards at the end wins the game.
