Addition War: Challenge

Addition War: Challenge is a Grade 1 card game for basic addition facts with a built-in accuracy check. Players turn over two cards, announce the sum, and compare totals, but classmates can challenge an incorrect answer. That extra feature makes careful calculation matter even when the familiar War format keeps rounds moving quickly.

Use it in a small group when students have enough fluency to benefit from repeated fact practice and peer verification. The challenge rule gives you a natural opening to ask students how they know a sum is correct. Create a free account to generate teacher-ready lesson support for Addition War: Challenge.
