Turn editing on in your course, then locate the activity you wish to activate groups for, then click Edit (three dots) > Edit settings. Then under Common module settings select an option from the Group mode drop-down menu (see above for option explanations). Also, be sure to check for additional group settings for the specific activity. For example, in the assignment activity, there are Group submission settings that can additionally be set that allow a group to submit one submission or require all members of a group to submit, etc.
Using groups filter
Once you have groups turned on for an activity and/or gradebook, you can now filter submisstions/students/grades by group using the groups filter that appears. Simply select the group you wish to view from the drop-down menu.
Using Groups to Restrict Access to Content
Please see Advanced: Adding Access Restrictions to Moodle Assignments for details about using groups to restrict access to Assignments. For other activities, resources, and topics areas, use the Restrict Access section to add restrictions based on group membership, among other criteria.
You will be able to filter your gradebook to show only a certain group.
