Fraction Match

  1. To play Fraction Match:
  • Arrange the cards face down in an array.
  • Take turns choosing 2 cards. If the cards match, keep them and go again. If not, return them to where they were, face down. You can’t keep more than 2 matches on each turn.
  • After all the matches have been found, the player with the most cards wins.
2. Use the cards your teacher gives you to create 4 new pairs of cards to add to the set.
3. Play another round of Fraction Match using all the cards.
