Game Rules
Play Fraction War the same way you play regular War with cards.
- Shuffle the index cards and deal out all the cards.
- Each player places his or her cards face down in a stack on the
table.
- Each player turns over the top card of the table. The player with
the largest fraction wins both cards.
- If both players turn over equivalent fractions, there is a
"WAR."
Each player places three cards face down and turns over the next card
in his or her pile. The player that turns over the highest card, wins
all ten cards. The first player to win all ten cards wins the game.
Tips and Tricks
If you are not sure which fraction is larger, change both fractions
to the same denominator. If two fractions have the same denominator, the
fraction with the largest numerator is the largest.
Example: 2/ 5 and 3/5 both have the same denominator. Since 3 is
greater than 2, 3/5 is larger than 2/5.
Or change one fraction so that both fractions have the same
numerator. If two fractions have the same numerator, the fractions with
the smallest denominator is larger.
Example: 1/3 and � have the same numerator, so 1/3 is larger since
the denominator is smaller.
