This activity is aligned to the Math 8 Common Core Standards on solving systems of equations. The problems are formatted to be printed on address labels (30 labels per page).There are 5 sets of 5 different systems and a reminder of when to choose which method. Simply print this page out onto the labels and attach to colored paper. This is a great review activity that includes solving systems by graphing, substitution, and elimination. You can plan on these problems taking students about 30 minutes.
