Just before the last term holidays, Apple released the latest version of their operating system for iPads and iPhones – iOS11.
iOS11 has some great new features (see https://www.apple.com/au/ios/ios-11/)  and it is worth updating your child’s iPad.
Simply go to Settings – General – Software Update. An update will be found and you can download and install this by following the prompts.
This will take some time, so allow about an hour and the iPad also requires at least 50% battery power or to be connected to power.

You will immediately notice that many of the apps have released updates to go with iOS11 so these should also be updated from the App Store.

If your child’s iPad is older and not compatible with iOS11, then perhaps consider a new iPad for your child for next year.
