Have a reverent child choose two cards by telling you the numbers. Flip the cards up. If they are a match, remove the cards from the board and sing the appropriate verse. If they are not a match, choose another child to have a turn. Continue until all of the matches have been found or until time is up.
Remember, games in Primary should not become so competitive that feelings are hurt or the Spirit and message are lost. Stress to the children that you are all working together and encourage them to be happy for one another.
