Fraction, Decimal and Percent War

Common Core Standards: 4.NF.2, 4.NF.7, 5.NBT.3, 5.NF.3, 7.EE.3

This game is designed for students to practice converting and comparing numbers in fractions, decimals and percents and aligns with the common core standards. It can be played as a whole class activity with the class being divided into different games being played or it can set up as a math center activity. I’ve included a completed answer key, plus I’ve also included a version of the answer key that the students can complete for themselves as a worksheet before playing the game where each row lists either the fraction, decimal or percent and they must fill in the other two values.

These cards can also be used by individual students where they must match the equivalent fraction, decimal and percentage. They can then compare their answers to the answer key.

Rules:
Fraction, Decimal and Percent War can be played with two individual players or by two partner pairs for a total of four players. If there is an odd number of players, three can play as a partner pair against an individual player.

The object of the game is to collect the most cards.

This game is played similar to the card game War. Each player will need a scrap paper and pencil for any calculations they cannot do in their heads. Mix up the Fraction, Decimal and Percent cards. The dealer deals the same number of cards to each player or team. Players flip over their top card and compare the two cards. The player/team with the higher valued card takes both cards and places them in a “win” pile off to the side of the playing area. Play continues with each player/team flipping over their top card and comparing them. If the two cards are equivalent, the teams “go to war.” They must place 2-3 (you decide – with only 36 cards I suggest 2) cards upside in the playing area and flip another card up which are then compared. The player/team with the highest valued card on the war pile, gets all of the cards for that turn.

When a player/team runs out of cards, their “win” pile becomes their new playing cards.

The game is over when one player/team has all of the cards and is declared the winner. Or if the game is being timed, it is over when time is called and the player/team with the most cards is declared the winner.

Suggestions for Differentiating this Activity:
• Place players of similar abilities in the same game. The higher groups can play as individuals and the lower groups as partner teams.
• You can also differentiate by removing some of the playing cards for the struggling learners – only use the smaller or common ones such as ½, ¼, ¾ etc.
• Additionally, you may remove a “type” of card. For example, only have students play with the decimal and percent cards, or only have them play with the fractions and decimal cards.
• Have higher learners create their own cards to play with.
