Below are a couple or resources that I have found through through the help and coordination of one of my fellow teachers, Chad Miller 6th Grade Social Studies. Mr. Miller sent me this link:
https://youtu.be/rFMmvNZsbr0. It is a video created by a high school teacher in Iowa.
https://youtu.be/MehzSAqxHHE This one was created by another teacher... I tried to track down where from, but didn't get very far. He does a great job breaking down the google classroom view as well for students.
Both videos explain how a parent may be able to view what a student views by either using your student's log in information or sitting with him or her to explore it together.
Google also has this information available: Parent Access
I hope this helps anyone who is still having any difficulties. Please contact me if you have any questions.
