Pass around a hat containing various math problems on a strip of paper. Provide two copies of each problem. Papers with the same problem should be both labeled as 1, 2, 3 etc. to make it easy for students with the same problem to find each other. Students pair up and solve their problem together. When they have completed the problem, they become the “teachers” of it. Now pairs of students join to make cooperative groups of four students. The “teachers” teach the problem to the “students”—their partners who haven’t yet worked the problem.
