This game can be played in small groups or partnerships to help students practice determining the missing addend in an addition sentence. It is played like Uh-Oh, Pop, or Bang. Students draw addition sentences from a pile and determine the missing addend. They keep the cards they solve correctly. If a "Kaboom" card is drawn the student must put all of his or her cards back except the "Kaboom" card. The player with the most cards, when the draw pile is empty, is the winner! It addresses Common Core standar 1.OA.8.
