This report-out method should be rapid and energetic. It works best when students have completed an activity, such as Roundtable, that lends itself to single statement summaries. Besides allowing for rapid exchanges (Sometimes this activity becomes a "Stand Up and Shout"), the value of positive interdependence (teamwork) is emphasized.
It relies on students having an easily designated identity within each team so that you can call on the "Number Twos" or the "Hearts" to serve as spokespersons. These designated students then rise, prepared to respond on behalf of the group. Each team responds in turn, giving only one response, in rapid round robin fashion. Depending on the number of answers and the number of teams involved, you may want to go through another rotation, calling on another group member to share one group idea (the "Number Fours" or the "Clubs" this time).
All students must attend to the sharing because they may serve as the next spokesperson. No ideas should be repeated. If student spokespersons find that all the topics on the team's list have been covered, they merely sit down and the rotation continues.
