You must setup a group and a group category first. See Create Groups.
You can create the assignment in the Groups area when you set up the group. Creating an assignment folder then creates a folder for each of the groups in the category. After that the settings are the same as individual assignments. See Create Assignments and Categories for further instructions on assignment settings.
To make an assignment after the groups have been created:
- Go to the Course Activities menu in the navbar, then choose Assignments.
- Click on New Folder.
- Enter a name for the group assignment folder.
- Select the Group submission folder option.
- Choose the Group Category (category that you created previously in Groups).
- See Create Assignments and Categories for further instructions on assignment settings.
