 # Fraction War

Junior (Age 9 – 12)

## Curriculum Goal

Junior: Number Sense

• Compare and order fractions (i.e., halves, thirds, fourths, fifths, tenths) by considering the size of the numerator and denominator.

## Context

• Students work in pairs, either in class or in breakout rooms on a video conference chat.
• Students should have prior experience with conceptual properties of fractions, including equivalent fractions.

## Materials

• In-person version
• Fraction cards (Appendix A)
• Fraction blocks/visuals
• Paper
• Pencil

## Lesson

Junior:

• Divide the shuffled deck of fraction cards between players.
• Each player turns over two fraction cards.
• 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 visuals/manipulatives.
• In the event there is an equivalent fraction, each player deals out three more cards (similar to the game W-A-R). The fourth card is flipped. The player with the greater fraction collects all the cards on the table.
• 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).
• Include cards with fraction problems that students must solve to determine the greater fraction.
