When Kindergarteners open their Chromebook, they will see a window open and their camera will turn on. They can scan their Clever Badge (which is a QR code with their name on it) and this will sign them into their Chromebook. A chime will play and there will be a green checkmark to let you know it was successful.
So, it's very important that the Clever badges travel with the Chromebooks when Kindergarteners are taking them to another class.
If students ever cannot use the Clever badge, they can always use the button in the bottom-right to enter the Google username and password.
