Addition Thirty-one

Addition Thirty-one is a Grade 2 card game built around one target: make 31 with five cards. Players draw and discard as they adjust their hand, continually checking whether the numbers can be combined to reach the target sum. The fixed goal encourages mental addition, flexible combinations, and planning instead of a stream of unrelated facts.

Use it in a small group when students are ready to think strategically about which numbers to keep and which to replace. Ask students how far their current hand is from 31 and what value would help most. Generate the lesson for Addition Thirty-one with a free Find a Math Game account.
