Assigned a second course via Google C lassroom, but I can't see it on my dashboard.

I assigned a new course for my students using the Google Classroom link that is set up in Khan Academy.  I had them click the link, and then sign into Khan using their current credentials.  (There credentials are different than their Google Classroom credentials due to district regulations.) I am looking in my dashboard, and I cannot see any work that has been completed for the reading assignment.  Do I need to add the course to my dashboard?  My students are currently 5th graders working in Khan Grammar and I added the 5th grade reading assignment.
