Lesson

Distribute the deck of fraction cards between all players.
Each player turns over a fraction card.
Players say the names of their fraction cards out loud and the player with the greatest fraction takes all four cards.
Players can determine who has the greatest fraction by finding the common denominator or using visual aids.
If two players have equivalent greatest fractions, each player is dealt three more cards (similar to the game W-A-R) and the fourth card is flipped. The player with the greater fraction collects all outstanding cards.
Play continues until one player has collected all cards.

Look Fors

Can students determine the value of the fractions on their cards?
Can students determine whether fractions are equivalent?
What strategies do students implement to determine the value of the fractions?

Extension

The player with the smallest fraction wins.
Add certain types of fractions to the deck to reinforce those fractions (equivalent fractions, simple fractions, mixed fractions, improper fractions).
Students turn over two fraction cards and add or subtract the fractions. The student with the greatest sum or difference wins the round.
