We utilize Google's G Suite for education to maintain Google accounts for staff and students. These accounts come with dozens of online services, including (virtually) unlimited storage for all the data with those services.
Google has produced the Teach from Anywhere site to help educators during the current health crises.
Every student and teacher has a Google Drive – a virtual space to store files. These are the files created by Google Apps, alongside any files you drag into your Google Drive. Learn more here.
Any file can go in your Google Drive – a photo, a Word document, anything. You can also keep special files that open in Google's applications. Built in to Google are the tools to make documents (like Word), a spreadsheet (like Excel), a presentation (like PowerPoint) and simple drawings. But you can add extensions to make movies, edit photos, make charts and a lot else.
You can view your email through Google's interface. Students under 13 cannot, by law and Google's terms, have an email address. But every student 9th grade and up has an email address.
You can create events on a Calendar, look at them from anywhere, and invite users from the @vashonsd.org domain to join those events. Also note that assignments from Classroom are automatically added to Google Calendar, organized by class.
The site you are currently looking at was made with Google Sites. It's an easy service for students to use to make their own websites, with two major advantages: 1) It's hard to make a Site that's an eyesore; and 2) It's easy to incorporate elements from Google services (Docs, Sheets, etc.). Teachers who need to make a quick "look at this" site to share with the world should also consider using Sites. Note: It is still possible, but not easy, to reach the old Google Sites, which was a very different service. Be sure to start with sites.google.com/new or use the Create button from Google Drive.
The Google Teacher Center hosts tutorials from a beginning level, all the way to certification for teachers who master Google tools.
There are two levels of certification teachers can acquire through Google.
Google's YouTube channel has hundreds of videos.
