One benefit to partnering students is that they get all the benefits of working with someone, but they fear rejection less, as they often do from large class discussions. Students typically do well choosing their own partners if teachers place clear consequences for a lack of progress. If not, number students or draw names from a hat randomly. You can also have predetermined partners according to abilities or compatibility.
Partner activities for graphic organizers can require more details, as two students will contribute. Divide the story in half and have the partnerships build the graphic organizer by discussing each half. Assign different aspects of the story, such as conflicts or vocabulary terms, to each partner and again, allow the partners to form a graphic organizer together. Partnerships require an almost constant dialogue to complete a graphic organizer.
