I initially though this was unnecessary, but that has changed. I am finding many platforms, such as EDpuzzle and Quizizz that enable students to log in with Google Classroom. The also allow you to make assignments in Google Classroom.
It would be great if we could just export our Canvas roster to Google with ease. (It would be even better if these developers supported Canvas, but I have found many that go from being free to $$$ to have features such as this).
