You can use this activity when you are teaching Fact Families. All you need is Dominos for the students to use. Demonstrate as a whole class, then break off into groups and individually and have students complete. They need to pick a domino, draw the amount of dots that their domino has, and then compute the 2 addition number sentences and 2 subtraction nubmer sentences that make up the family. Then, you can bring it back to a whole group activity and share out.
This can also be used as a math center.
