How do I assign a group assignment?

Please review the instructions here: How do I assign an assignment to a course group? - Instructure Community

Here are some important things to bear in mind:

• Always set groups in stone before allowing submissions.
  • A lot of issues can arise if students submit assignments without being in the correct group. If group memberships are altered after a submission, the submission will appear to "disappear" completely and in practice will require the affected groups to resubmit. 
  • The best practice is to force students to establish the correct group membership well in advance of any submissions. If group membership needs to be amended later, then they should do so in concert with the instructor who can inform affected students of the need to resubmit work, if applicable.
  • Note that individuals should be in a "group", even if they're submitting as an individual.
• If the assignment gives students the option to submit by group or individual, the best practice is still for the student to be assigned to a group (either by themselves or by an instructor).
• For multiple group assignments:
  • If you have multiple group assignments within a course, you can choose to have a different group set for each assignment. This is perhaps the "cleanest" way to arrange things but if the groups are the same, or nearly the same, across multiple assignments, then it may seem inconvenient to ask students or instructors to reassign groups for each submission.
  • One option is to use use "Clone Group Set". After each assignment, clone the previous group set and edit the next assignment to align with the clone. You will have different group sets for each assignment, but you this prevents the need to re-do all the group memberships each time.
  • Another alternative is to keep the same group set throughout. However, this does require some management if groups may change between assignments. Let's assume you have a group set and everyone has submitted the first assignment and you've graded all the submissions. The next step must be to edit that first assignment and check the box that says "Assign Grades to Each Student Individually" then click "Save". This won't change anything but essentially locks in that assignment's grades. Do this after every assignment, even if there are no changes to groups for the following assignment, because all previous assignments need to be locked in if you ever make future changes to the group set. Then, when you want to make changes to a group set, go to People, the relevant group set, then make changes. You'll receive a pop-up that asks if you want to clone the group set. You do not. You want to instead "Change Groups" (one of the two options you'll be faced with).
