A great investigation for your class to try out. They will need to use their addition and subtraction skills, as well as working systematically to find a solution. The activity includes ideas to extend the more able, making it suitable for all. It's best to use real dominoes, but don't worry if you don't have any as a photocopiable sheet is provided.
