This game is for addition and subtraction facts 1-12 . It is from the Addition and Subtraction Basic facts games lapbook, which we purchased for half price on a sale at Knowledge Box Central. I put each of the games from this lap book in it's own file folder, for easier play and use. To play we use two dice; the dice are rolled and either added or subtracted depending on which game board you want to use. The answer is then covered with a button. The first player to cover all his numbers "blacks out" the board and is the winner.
