Guided Access

Some students need some help to focus on the job at hand. On the  iPad, there is a lovely tool called Guided Access. This deactivates the Home Button so the student can't just pop out of the app. It is quick and easy to activate.

Go to Settings, then General and select Guided Access

If the student triple clicks the home button, where it says "Start" now, it will say "Resume" so you can carry on if needed.
