How can I organize my Students into teams for WikiProjects and smaller groups for Discussions?

Group Sets contain two (2) or more collections of students, called Groups. Groups allow Teachers to assign Students to "teams," in which they can work on a project or engage in a discussion together.
Teachers can create Groups from the Edit Roster tool or when creating a Group WikiProject or Group Discussion.

Pro-tip: All created Group Sets and Groups (for both WikiProjects and Discussions) can be used in future activities and managed from the Groups tab under Manage Class > Edit Roster.
