Print four copies of each card page to make one deck. There should be 48 cards (there are no Joker cards, although that's always an option if you can find a use). On the back of those card sheets, print the crazy pattern page. This will stop the students looking through the thin cards (it really works). Cut the cards using the school guillotine. In the class, students make groups of three or four, and one deck of cards is given to each table. Students are dealt four cards each, and they put down and keep any pairs they might have (there are four copies of each card in a deck) and then the remaining cards are put in a pile in the middle. The game moves clockwise. The winner is the person with the most pairs. For the detailed rules of the game, look at the included rule sheet, which should also be printed and given to each table.
