Instead of using an in-class model in which one person shares with the whole class (one at a time), or using a pair-share method, consider a reset and try the use of trios.
The “TRI” method:
Assign trios in advance (ideally purposefully, but randomly-generated trios work, too).
Assign sharing order and trio roles in advance (see suggestions below).
Provide a time frame for each trio, including the time limit for each sharing person.
