There are 11 questions each on their own page. Print off one set, shuffle the pages, and hang the questions around the room. Students then start at any question and solve the system on the card. When students solve the system they scan the other cards in the room for their answer. When they find their answer they go to that card and write down the letter in the upper left hand corner. Students continue until they've answered all 11 cards. The instructor can check the work quickly by checking the order of the letters. A correct path would have the letters JINGLETODAY, but keep in mind students can begin at any one of these letters and cycle around. I usually partner students together when completing this activity.
