2-DIGIT SUBTRACTION CARD GAMES Materials: Four pages of pictures following these instructions (equation, number line, measuring tape, written algorithm). Number of players: 2-4 Directions: Print the four pages in 4 different colours, laminate and cut each page into 12 cards (making 48 cards of 4 different colours). Shuffle the cards. Follow instructions for these games: Snap. Two players, cards divided equally between players. Together, the two players play the top card of their deck face up in front of them. First to call snap when two cards show the same number wins a point. The player with the most points wins when all cards played. Rummy. Two to four players, deal out 7 cards to each player. Remaining cards face down in middle with one card face-up beside deck. Players put out any doubles or triples. Players in turn pick up a card (either the top face-up card or face-down card) and place a card face-up on the face-up pile. Doubles and triples are put out as they are formed. The winner is the first player to put out all their cards as doubles and triples. Concentration. Place all cards face down on table. Players take turns selecting 2 cards. If they are the same, keep the pair and take another turn. The winner is the player with the most pairs when all cards used. © 2007, 2013 QUT YuMi Deadly Centre
