Awesome Screenshot extension: Virtual grappling hook for grabbing screenshots. Crop 'em, annotate 'em, make demonstrations make sense.
Power Tools Google sheets add-on: Suite of tools that have potential to work mind control on spreadsheet cells. Lately, I'm a fan of the Data Random Generator. Pair that with a class roster and mix up groups of various sizes with the click of a button. Sometimes students choose with whom to work; other times I group intentionally; and yet other times we're jokers who roll the proverbial dice.
Giphy site: If pictures are worth a thousand words, what's the going rate for moving pictures? This collection of GIFs turns documents (hyper or otherwise) into -- pow! -- fun Saturday morning cartoons, not to mention livening up Google forms, Tweets, or even e-mail.
Classroom Organizer site: For a class library, it's like Uber meets the Batmobile. More flexible and faster than circulating books via loose-leaf scribbles kept on a clipboard.
Diigo extension: When resource listicles fly around the Internet, this social bookmarking site plays Robin -- a worthy sidekick who has my organizing back.
