The navigation is a vital component to ensure that students have access to the correct areas of your course. In order to maintain consistency across grade levels and schools, the navigation guidelines have been put in place. If you have something else you would like to add to the navigation of your own course, work with your Ed Tech Coach to discuss best practices and implications of such an addition.
Items such as Assignments, Quizzes, Discussions, etc. are not included in the course navigation. Use Modules to organize and share these items with students.
