The Fast-Paced Addition Card Battle
SUM SLAM! is a flexible addition card battle for Kindergarten through Grade 4. Both players flip two cards, add their values, and compare the sums; the higher total wins all four cards. Ties create a SUM SLAM WAR, with more cards flipped until one player produces the greater sum.
Use it for partner work when students need repeated addition practice in a simple, fast format. You can adjust the deck or card values to keep the sums appropriate for younger or older students while preserving the same game structure.
