There are 20 Powers with corresponding definitions and checks that are to be matched up. I usually have the students in groups of 3-4 to cut down on the amount of copies, Also, the pieces last longer if you laminate the sheets first. It's pretty self-explanatory, I found all the Article II powers and roles I could (formal and informal) and threw them into a matrix. I also would suggest having the kids do just the first two columns of matching at the beginning of your unit, then do it again, incorporating the checks at the end. Alternatively, this could just be a great study guide. They love games!
