Our school district has made the shift to Google about five years ago. I was seriously a holdout when it came to creating new docs in the drive in favor of applications like Keynote and Pages. When my creations no longer cooperated with the drive, I had to make the shift to applications like Sheets, Docs, and Slides. It was easier than I like to admit, and thanks to people like Kasey Bell, there are lots of cheat sheets out there that make learning Google apps much easier to learn! By subscribing to her blog, she will give you a free e-book that has cheat sheets for all of the Google apps in the suite!
Definitely check it out!
Which way is up?
