Star Drive Files
Google Classroom allows you to collect digital student work… into YOUR Google Drive. When you “Make a copy for each student” you now have 31 to 201 copies of the exact same file name in Google Drive. When you search Google Drive you can filter your files by Starred so only the “good stuff” comes up instead of all the student files you collected.
Keyboard Shortcut
Single click on the file in Google Drive and press S.
In the Document
Next to the file title is the ability to star the document. As you are creating your documents, click on the star.
Filter for Starred in Google Classroom
When adding files from Google Drive to Google Classroom notice there is a tab for “Starred.”
Manually Filter
When searching Google Drive when adding files to a Google Classroom assignment you can add is:starred into the search box to only return results that are starred.
Star Files Shared with You
If a fellow teacher has a cool file that is starred and they share it with you, it is NOT starred in YOUR Google Drive. You get to choose what is starred in your own Drive. Make a point of starring any files shared with you that you might want to use in Google Classroom.
