Addition fact fluency is an elusive treasure. Help your students become quicker with this fast paced card game. Students flip over cards, answer the problem and compare it to the other players. If there is a sum that matches another they have to say, "OH SNAP!" first to win all the cards.
Set includes four color coordinated sets of 13 cards each. There is an answer key as well.
