Group Activity 209 Card Games with Fractions Materials: A deck of fraction cards for each group. These can be made from index cards where one side of the card is blank, and the other side has a fraction written on it. The deck should consist of several cards of each of the following fractions. Estimated time: Instructor discretion In this activity, we outline three different games for students to play in their groups as a fun way to reinforce skills of adding fractions, recognizing equivalent fractions, and ordering fractions. Game 1 “Blackjack” Group Size: 3 1. In this game, one student in the group will be the dealer, and the other two will be players. The dealer will deal each player one card face down and one card face up. Then the players individually may elect to have more cards given to them (face up). The goal is to have the sum of the fractions get as close to “2” without going over. 2. Once the players have taken all the cards that they want, they will display their cards face up for the group to see. The player who has a sum closest to “2” without going over wins. The dealer will resolve any “disputes.” 3. The members of the group should rotate after several games so that each person has the opportunity to be a player and to be the dealer. Game 2 “War” Group Size: 2 1. In this game, each player should start with half of the deck of cards. The players should shuffle the cards and then stack them neatly face down on the table. Then each player will select the top card from the deck, turn it over, and place it on the table. The player who has the fraction with the greatest value “wins” that round and takes both cards. 2. Continue overturning cards and deciding who “wins” each round until all of the cards have been overturned. Then the players will count the number of cards they each collected. The player with the most cards wins. Game 3 “Bingo” Group Size: The whole class 1. Each student gets five fraction cards. The instructor will call out fractions that are not in lowest terms. The students must identify whether the fraction that was called is the same as one of the fractions on their cards. For example, if the instructor calls out “three-ninths,” then students with the fraction card would have a match. 2. The student who first matches all five cards, wins. 13 1 4 , 1 2 , 3 4 , 1 6 , 1 3 , 2 3 , 5 6 , 1 8 , 3 8 , 5 8 , 7 8 , 1 5 , 2 5 , 3 5 , 4 5 , 1 10 , 3 10 , 4 9 , 2 9 , 3 7 Group Activity
