You will want to reboot your iPad if you are having issues, if it is slow or unresponsive or if apps start to crash in order to reset it. This will help your iPad work better because rebooting your iPad will flush all the apps from memory and help it run better.
In order to reboot your iPad, all you have to do is hold down the sleep/wake button until the iPad prompts you to slide the button from left to right to reboot. If this process isn’t working, hold both the sleep/wake button and the Home button at the same time. This will force the iPad to shut down. Then, just hold the sleep/wake button for several more seconds to prompt the iPad to start back up.
