Back in middle school and high school we'd play these fun math games where you'd have to draw a chart and figure out who had what. Example, there are five people, joe jon julie mike and amy. Each has a favorite color. Mike doesn't like red, but amy doesn't like blue, etc etc. What are these called and where can I get more? They were a blast!!
