Breakout rooms in Zoom allow a meeting host to break a meeting into smaller sub-groups for group based activities. Participants in the meeting can then have discussions with anyone else in their breakout room, and the host can float between the groups to answer questions as the session progresses. At the end of the group work session, the host can then call participants back to the main room.
