Press and hold the Sleep/Wake button for a few seconds until a red slider appears, then press and hold the Home button to force the app you are using to close.
If that doesn't work, turn iPad off, and then turn it on again. Press and hold the Sleep/Wake button until red slider appears, then drag the slider. Press and hold the Sleep/Wake button until the Apple logo appears.
If that doesn't work, reset iPad. Press and hold the Sleep/Wake button and the Home button for at least 10 seconds, until the Apple logo appears.
