Over the last couple of months I have held some after school sessions that were designed to help teachers get better acquainted with Gmail, Calendar, and Chrome. If you were not able to attend any of these sessions there are still some things you can venture out and learn on your own.
One of the best resources we have is something you might not have even noticed. Last year I pushed out an extension that is called G Suite Training to all of the certified staff. The is an AMAZING app that provides you will answers to basic questions about a variety of G Suite apps such as Drive, Calendar, Gmail, and Sites. The extension is located in the upper right corner of your screen and the information it provides changes depending on the site you are on. THIS. IS. AWESOME! It is like having an assistant sitting with you at all times who is able to answer your technical questions about a variety of different apps!
The other place where you can find quite a bit of basic information about Google Apps (G Suite) is in the Google Training Center. This training center is more user friendly than ever before. In addition to fundamental and advanced training, there is also a section that is dedicated to how to use Android devices and Chromebooks.
The Great Plains Google Educator Group (GEG) is a good site to join to connect with other teachers who are using Google Apps in their classrooms. Even if you are only comfortable "lurking" there are still lots of tips and tricks you can pick up from this community.
