We've been playing several games with dominoes recently during math. The two halves of a domino provide a lot of opportunities to practice addition strategies, among them:
-Counting every dot starting at 1
-Counting on from one of the numbers
-Counting on from the greater number
-Noticing and practicing doubles like 4 + 4, or near doubles like 4 + 5
-Working from a known fact and mentally adjusting the total
In general we work on gradually encouraging children to choose a strategy that is more efficient than counting every dot from one. But this takes time and practice...
Students learned a version of the traditional domino game. Then we learned Domino Top Draw (like War). Most recently we've learned Domino Add and Compare (like Top Draw but with the added requirement to write an addition equation to match their own and their partner's domino then note whether their own total number of dots is less than, greater than, or equal to their partner's).
