Click on the line between content items or click the 'plus' icon.

Click "Discussion" from the Content Creation menu.

Click on the gear icon to access the discussion settings.

Click "Assign to groups" at the bottom of the settings.

Here, you can create a custom group for this discussion.

However, if you click the "Custom" option, you will find you have a few other options!

You will be able to make groups custom, randomly assigned, or self-enrollment, but you can also reuse group sets if you've made groups in your course before.

When reusing groups, make sure to note that if you move students, the student moves groups and loses their work in the previous group!

Click "Save" once you're happy with the groups you've created.

Once you return back to the Discussion settings, you will see that the label will indicate the number of groups present in the discussion.

Click "Save" once you're done managing your discussion settings.

You'll be able to click through the groups to see how each group discussion is going!
