Teachers can sign up for EdPuzzle using this link and choosing the sign in with Google option. Or if teachers just visit Edpuzzle.com and sign-up for a Teacher account with their school google credentials, they'll just have to select "St. Stephen's Episcopal School" on the "Choose your School" screen and they'll be automatically upgraded.
If prompted, you may consent to terms and conditions on behalf of your students.
After verifying their email, teachers will be able to import their Google Classrooms on the "My Classes" page, and then import their students.
As long as teachers have imported students from the "Students" tab in "My Classes" for each of their Google Classrooms, students won't need to sign up at all – When they click an Edpuzzle assignment from Google Classroom they'll just sign-in with their Google account.
Some students have reported problems using EdPuzzle (video won't start or can't answer questions). If that happens, open a Guest window in Chrome and sign into Classroom from there. See screenshot to the right. Click your image or initial in the top right corner of the Chrome window, then click Guest.
