This domino activity is fun for a group, partners, or even a relay race. Students solve the problems on the right of the card then match it to an answer found on the left of another card. It does not matter which card they start with since it will form a continuous loop (students can be really creative with their shapes). You will need to cut out the cards before giving the set to the students, since they are printed in correct order. I prefer to use different colored cardstock for each set to help keep track of the cards for each team (plus it really helps when one falls on the floor). I also laminate them for durability and reuse. Each card has an answer on the left and a problem on the right for a total of 18 cards (6 per page).
