You can create a group assignment by using the Group Assignment checkbox. Canvas uses group sets to assign group assignments, and each group within the group set that is assigned to the assignment is required to complete the assignment. When creating or editing a group assignment, you can assign an assignment to specific groups. You can also set different due dates and availability dates for a group within an assignment that is assigned to the rest of the class.
You will need to assign a group set as part of the assignment. You can add an existing group set, or you can create a new group set as part of the assignment and add students to groups later. However, if you create a group set with self sign-up or manual group assignments, you will not be able to use the group set until users have been added to the subgroups. Student-created groups cannot be used for group assignments.
When differentiating groups in assignments, students can only view the assignment if they are a member of an assigned group. Otherwise the assignment does not appear in the student's assignments page. Grades cannot be assigned for students who have not been included in the assignment, and assignments that are not assigned to a student are not factored into overall grades.
When Multiple Grading Periods are enabled in a course, assignments are also respected against closed grading periods.
In Course Navigation, click the Assignments link.
Click the Add Assignment button.
Enter a name  and description  for your assignment, as well as any other assignment details .
Click the This is a Group Assignment checkbox.
You can choose to assign grades to students individually by selecting the Assign grades to each student individually checkbox.
If this box is left unchecked, all the students in the group will receive the same grade.
To select an existing group set, click the Group Set drop-down menu . To create a new group category, click the New Group Category button .
Note: Groups created by students cannot be used for Group Assignments and do not appear in the drop-down menu.

Note: This warning message will not appear if everyone in the course or all course sections are assigned.
If you submit an invalid string of due dates and try to save the assignment, Canvas generates an error notification.
