Think of Google Drive as online storage as well as a place to create new Docs, Sheets, Slides, and other Google Apps. 
Docs are the Google equivalent of Word. 
Slides are the Google equivalent of PowerPoint/Keynote. 
Sheets is to Google as Excel is to Microsoft. 
Create a quick feedback form or sign-up sheet using Google Forms. Responses can be immediately pulled into Google Sheets. 
Make a website quickly and easily with Google Sites. 
Create a virtual learning environment and go paperless at the same time with Google Classroom.
