Students pair up and shuffle their cards.
They deal the cards out evenly and stack them face down in front of them. Both students turn over their top at the same time. They multiply the 2 cards and shout the answer. If a tie should occur, keep turning cards until someone wins the pile. When all of their original stack has been played, they count their winnings.
