Add Doc to Classroom for Chrome
More About Add Doc to Classroom
The button opens a new window which takes the Doc URL and gives it to Classroom (https://classroom.google.com/share?url=...), all on your computer.
From there, choose which class to share it to, change the description and customise the task just like you would on the normal Google Classroom™ website.
This extension is not associated with Google.
The extension uses the images of the Classroom Share button (https://developers.google.com/classroom/guides/sharebutton)
