What are Canvas Modules?
Modules allow instructors to organize content to help control the flow of the course.
Modules are used to organize course content by weeks, units, or a different organizational structure. Modules essentially create a one-directional linear flow of what students should do in a course.
Move or Reorder a Module in Canvas
You can move or reorder modules after you've created them. You can manually drag and drop the module, or you can use the Move To option, which is also accessible for keyboard users. You can also move or reorder module items.
