When working with group activities, we should be aware of a series of recommendations: 

1. Work groups can be created at the time of setting up the assignment, but it is recommended to create the groups in advance.
2. If a student joins after the activity has been submitted, they will not have access to that submission.
3. If a student moves to another group, they will still appear with the grade of the group they belonged to when the assignment was submitted.
4. If there is a student in the group who has an exception, the group inherits that exception in the activity in which it is participating. 

A good practice for this type of activity is to enable class conversations. This will allow the members of each group to interact and have a discussion space within the activity.

It is important to remember that it is recommended not to move students between groups once submissions have started. This is especially important in self-enrollment groups, where a student can "jump" from one group to another. It is recommended to close the enrollment period (thus closing the period in which the student could change groups) before making the group activity available.

Creating a Group Activity

When configuring the activity, in the general settings, we will indicate that it is a group activity by clicking Assign Groups.

Once inside the configuration, we will have the option to create a grouping and groups for this assignment, or reuse groups that we have already created in other groupings. 

Working in a Group (from the Student's Perspective)

Students in a group see the assignment and can edit and modify the draft submission of the current assignment. At all times, they can see who is editing it.

The work they do on behalf of the group is saved, but not submitted. Another group member can continue working on the assignment later. All group members can keep track of the most recent version of the work.

Once the work is finished, only one student from the group needs to submit the assignment and it will be ready for the instructor to grade the group activity.
