Use the Content Tool to structure your course. First, create modules to organize your course into units. Next, create topics within each module to link to materials and activities and provide a virtual "checklist" for your students to track their completed work.
If you organize all your course material in Content, students can easily tell that they have completed all their assignments and avoid checking multiple places to find their work. As students progress through Content, and finish activities (quizzes, discussions, etc), they will receive a check mark in Content to show their progress.
