Chords are the best way to start, first the basic open chords, then barre chords. It's also good to teach some basic theory while at it, she's got to learn her intervals and her fretboard so she'll be able to learn how to make chords and how to play them with different voicings. Also basic scale knowledge. Learning scales will help her learn the fretboard, and the Major & Minor scales along with their modes will offer a shitload of knowledge.
