Here's a sweet spin on both classic dominoes and flashcards! One side of the card has Hersheys Kisses ® arranged in instead of traditional domino 'dots' and the other side has two mathmatical subtraction/addition problems. You can play either a regular game of dominoes, or turn it into a learning game by matching sums & differences. Perfect for adding a little incentive to math drills! 36 double-sided cards and instruction sheet included.
