Do you need to create a math center where students can practice their subtraction facts in an interesting, novel way? Dominoes are the perfect center. Purchase enough dominoes at your local Wal-Mart store to fill a gallon-sized ziploc baggie. Purchase varying dominoes with different numbers on them. There are dominoes that have numbers 1-6 on them, dominoes that have 1-9 and dominoes that have 1-12. Print this template and include it with the dominoes to provide students a fun, easy way to practice their subtraction facts. Have them pull out one domino at a time and document the dot pattern on their paper. Then, show them how to set up their math equation with the larger number first and then the smaller number. You'll have a great math center for weeks!
