Are you looking for a fun way for your students to practice finding the value of exponents, instead of the usual worksheet or technology resource? If so, this classic 'war' game will suit your needs. There are 64 playing cards, and it is designed to be played with 2 players. It can be used with up to 4 players, but it will be a short game. I made this game for my math students to get some practice in evaluating exponents, while interacting with another student. I included an answer key for students to use to check their answers, so they can get immediate feedback on whether their calculations are accurate or not. I find the most common error students make is evaluating a problem like 2 to the fourth power as 8 (because they just multiply the base number and exponent) instead of realizing it is calculated as 2 x 2 x 2 x 2=16. I plan on continuing to use this math game in my math rotations throughout the year to keep the students fresh on the concept, which is an essential concept to know for solving algebraic expressions.
