This is a self checking activity for combining like terms with negative numbers. I love using this for review or a math center. You will need to cut apart all 18 dominoes, I usually laminate them first. Then have students solve problems and connect the dominoes together until they are in a straight line. There is a student recording sheet available in this activity as well so you can make sure all students are showing their work, especially if they are completing this in small groups.
