Google Drawings is like a digital poster board. Or sheet of paper. Or a blank slate waiting for your great ideas.
Sadly, many educators don’t know about it or know what it does. Maybe part of the reason: when you click “new” in your Google Drive, Drawings is under the “more” tab. (What a shame … one of my favorite Google tools treated like a second-class citizen.)
Inserting Google Drawings into a Google Doc is a trick I use when I want something a little more “fancy”.
