Play this game with a buddy during math center time. Roll the dice, add 2 to get your final answer. Find answer on math mat and cover with a chip. Student to first cover the mat is declared the winner. Problems (rolls) can be written down. I prefer to not copy the problem because it makes the buddy pay attention when it isn't his turn. I always remind students you have to monitor your buddy so that you are sure correct answers are being covered! Good mental math practice.
