Canvas has many options for using the Assignment tool for students. Students can use the assignment feature to upload outside documents or to complete the assignment in the Text Entry option. Students also have the option to upload media or insert a hyperlink.
The instructor can add a rubric or other additional documents for you to use for completing the assignment. Make sure to locate and read all the additional materials before completing and turning in your assignment. You can double-check your work to make sure it has been accepted into Canvas.
