This cooperative learning activity is called a "Round Table". Each student in a group of 3 or 4 has a handout with given information. In the first round, each person completes the "Person 1" objective (in this activity, performing the four basic operations with complex numbers ASMD). Then the papers are passed to the left or right for Round 2. However, before starting Round 2, each student must check the previous person's answer. If it's incorrect, they must correct it and explain why it is incorrect. This continues until all four parts are completed. Each student will complete four different objectives for four different given statements.
