MEAN WAR

MEAN WAR is a data game for Grades 5–7 that turns the calculation of mean into a card-game comparison. Each player flips the same number of cards, finds the average of those values, and compares the result with the other players. The highest mean wins the round, and tied averages trigger a War round with a new data set.

Use it in a small group when students understand the mean and need repeated practice calculating and comparing averages. Changing the number of cards used per round can make the data sets simpler or more demanding. Create a free Find a Math Game account to generate teacher-ready lesson support for MEAN WAR.
