SUM SHOWDOWN

SUM SHOWDOWN is a fast addition card battle for Grades 1–3. Each player flips two cards, adds the values, and compares sums; the higher sum collects all four cards. Equal sums trigger a War round with two more cards per player, so tied addition facts create an even larger prize.

Use it for partner practice when students are building mental addition fluency and comparing totals. Face cards extend the range beyond 10, making the game easy to adjust for students who are ready for larger sums.
