Before starting a tech/iPad program for preschool aged children, it's important to teach the basic foundations of Touch and interaction with tablet devices. You wouldn't put a child in front of a computer without teaching him or her how to handle the mouse and keyboard - the same preparation goes for an iPad, Nook, Kindle, or any other tablet.
These materials will walk you through the Top 5 Gestures that you should teach students first, with mastery criteria provided for each one:
Free apps are also listed that can be used to help teach these topics. I hope this is helpful and that it can make learning with tech fun for everyone!
Please follow me or check back often as I'll be uploading more specific, detailed teaching plans for each type of gesture. In the future, I will also create more material about what to do next after the Basics of Touch have been mastered!
