The first thing I would recommend is that you either restart or reset your iPad (or both!). To do:

Restart: Hold down the power button until the power off slider appears. Slide it off. When the iPad finishes shutting down, hold down the power button again until the Apple logo appears.

Reset: Hold both the power and home buttons until the screen goes dark and the Apple logo then appears (the slide to unlock screen may or may not appear). Once the logo appears, release the buttons. After a time, your homescreen will appear. Please note that it may take some time for the Apple logo to appear or for your homescreen to appear (or both). This is normal. Eventually, the homescreen will appear.

You'd be surprised at how much either or both of these two procedures help fix the iPad's quirky behavior. If it helps, yay! If it doesn't, do let us know and we'll take another crack at it. Good luck.
