The teaher asks a quetion. The group convenes and makes sure each of the four members knows the answer. The teacher calls a number, and students with that number raise their hands to respond.
Students first think by themselves.
Students pair up and each pair discusses the topic. Then pairs share their thoughts with the class. Four or five students write simultaneously on a large piece of paper or on the board, providing main concepts, supporting elements, and bridges representing the relationship between ideas in a concept. Upon returning to their teams, students take turns teaching the group about their topics. Students are quizzed on all aspects of the topic.
