If you work in a school that utilizes GSuite, you really need to check out the YouTube channel Google for Education has.
There are numerous playlists that serve as tiny chunks of professional development for you. (And don't hesitate to share with your colleagues near & far!)
I subscribed and I receive an email each time they upload a video. I find the EDU in 90 super helpful - they are 90 seconds long and cover something about GSuite. Tips/tricks/information and more.
Here are links to a few of the videos I've found to be helpful ↬
EDU in 90: The Latest, January 2019 is their most recent and covers Google Classroom, their computer science program "CS First", and more.
EDU in 90: Teacher Center Resource Hub is another great video. The resource hub is fantastic place for teachers to learn more about GSuite.
EDU in 90: Our Favorite Chromebook Shortcuts is one of my favorite topics ... keyboard shortcuts!
... and if these are appealing to you, be sure to check out the channel and be sure to click the red SUBSCRIBE button!!
