Activity 2 Fraction Match
Your teacher will give you a set of cards for playing Fraction Match. Two cards are a match if one is a diagram and the other a number, but they have the same value.

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.
Use the cards your teacher gives you to create 4 new pairs of cards to add to the set.
Play another round of Fraction Match using all the cards.
