Logging IN to TinkerCAD
Signing your students into TinkerCAD is very easy if your school uses Google accounts for Google Apps for Education or Microsoft accounts for Office 365.
Step One: Go to the TinkerCAD website and click "SIGN IN" (very important to make sure the kids click "SIGN IN" and not "SIGN UP")
Step Two: Have the students click "Sign in using Social Providers". This will bring up a list of Social providers that you can choose from. (Facebook, Google, Yahoo, and Microsoft)
Step Three: Now have the students choose the service that your school uses. NOTE: The very first time your students do this, they'll be presented with a dialog asking them to "Allow" the connection. Have them click "Allow". This will only happen once.
