Microsoft What? - The Basics of Microsoft Word
This lesson on creating a Microsoft Word document is Windows-based, but can easily be updated, not only to newer versions of Windows but also to iMac. The step-by-step directions are well written and this means not having to create the whole thing yourself. You could even print it out and then read it aloud as you guide your young learners along these steps; that way you wouldn't have to update anything.
