In Canvas, the Attendance (Roll Call) tool allows instructors to record their students' attendance and automatically adds a "Roll Call Attendance" column to the Gradebook. 

If you do not see the attendance tool in your course it may have been hidden on the course menu. To add a hidden tool to your course navigation menu, see How do I manage Course Navigation links? 

For details on enabling and using this tool, consult the Attendance (Roll Call) guides in the Canvas Guides.
