The leader is in charge of making sure the group stays on task and that everyone in the group is participating. If there is a question or a particularly difficult problem the leader is in charge of calling for help and articulating the question to Ariel or Graham.
At the end of the day the leader is in charge of sending the link for the completed worksheets to Graham.
The note taker is in charge of writing everything down on the worksheet so that everyone has the notes later on. Answers on the worksheet should be detailed and show work, not just the answer to the problem.
When sharing your answers with other groups or the whole class the reporter is the person who will present the answers that the group cam up with.
The reporter is also in charge of notifying Ariel or Graham that the team is done with a worksheet.
(Only in groups of size 4)
The cheerleader is in charge of recognizing the accomplishments of other people in the group and complementing them on those accomplishments. These could be figuring out the solution or next step in a problem or asking a good question or restating something clearly so another group member can understand or refocusing the group and helping them stay on task.
