My iPad is not working well, the apps are stopping and the iPad is turning off

Try holding down the lock/home buttons at the same time for 10 to 15 seconds. the apple logo will appear and then it should start back up.

Thank you so much. Something froze -- I could get to my current book and game but not do anything more. Same with internet. Now everything works. Didn't know there was a way I could reboot or whatever.
