You can create groups to help organize students for collaborative activities. Students can select their group preference if you create the group set to allow for self sign up.
NOTE: Students can sign up for their own groups by following steps 1 and 2. They can also continuously move from group to group. Self sign-up can be disabled after all students are placed in groups by clicking the pencil icon at the top of the page next to the group set name, and unchecking the "Allow self sign-up" box.
