How to Create a Discussion
Creating a Canvas Discussion
In your Canvas course, click on the Discussion link  in the Course Navigation Menu, then click the Add Discussion button .
Type in information for your discussion, including the Title  and a description  of the topic or questions. You can use the toolbar of the Rich Content Editor to add formatting and insert media elements.
Check the boxes for any of the discussion Options  provided. We recommend using threaded replies for easier viewing. We recommend checking the box for Graded discussions (even if they're worth 0 points) so faculty have the SpeedGrader interface and so any files uploaded by the student are not counted against their limited file storage.
If this is to be a Group Discussion, check that box . You must set up at least one Group Set first.
You can set time parameters for the discussion using the Available From/To options .
Don't forget to hit Save! Click Publish and your discussion board is ready for your students.
