Name the class, set how long it runs, and list the sites it needs. Everything else stops opening until the session ends — and afterwards you get a report of what actually happened.



Name the few sites the class needs. Everything else stops, so nothing new slips through.
Set 45 minutes, or run it until you end it. The session closes itself when time is up.
Tabs already sitting on something else are pulled into the session too — and returned afterwards.
A session can't be ended early without it, so a child can't simply switch it off.
Joining a class with a school or family Google account isn't broken by the block.
Time on task, time away, how many times attention left, and every site turned away.
