Google drawings are one of the most versatile tools. I use them all of the time in my classroom. Everything in the picture below is a google drawing.
All of the posters in my classroom are google drawings. The backgrounds can be changed and resized to cover the entire page. Shapes can be typed on and then moved to any spot on the document. Things can be put anywhere on the page without having to do any extra steps. Google drawings are one of the least utilized tools in the google suite.
