Hi, welcome to the iMore forums,
You can turn it off by pressing and holding the on/off button thats on the top backside (near the right corner) of the ipad.
After a few seconds you will see a slider in the screen to turn of the iPad.
To turn back on, just press the button again for a few secs and the apple logo will appear to show it's starting up.
If somehow the iPad gets 'stuck' if you use it, then you can also force it to shut down, for that you have to press both the on/off and the home button at the same time and hold it until the Ipad turns off. You won't get a slider, it will just turn off.
Then you can start it again with the on/off button.
