For instance you have an Ipad and want to use your district Google Docs account. That wouldn't have been possible with the old system, now you can access your district Google Docs on any device that has a Google Docs Application. Use your district account to login to your android or Chromebook devices to access Google Services. Create a quiz and share it with your students and the results will come back to you in a nice little graph. There are a ton of great things you can do now and I hope more folks will start using these tools.
