I hope that you are going to teach them to read music. If yes then what I did after they learned all 6 strings, note lengths, rests etc I would ask then what they wanted to play. I'd get a list from them then go to Musicnotes (http://www.musicnotes.com/) and DL a song or two that I could easily transpose and change to meet their skill level. Note that paying for music that you use to teach is tax deductible. You can do a lot with hole, half, quarter and eight notes in the key of C. This usually inspires the student to want to learn more. You can rewrite the song in BiaB, a DAW or like myself the free MuscScore2 (https://musescore.org/en/2.0).

If they just want to learn chords then google/bing songtitle and chords.

On a side note for the songs I rewrote I usually include a CD containing BiaB backing tracks. I would have a number slow to actual song tempo backing tracks. If you can't play it slow you can't play it fast.

Also I have had great success teaching the A pentatonic scale then jamming a 12 bar blues in A with the student.

Just my method of teaching. YMMV.

Doc-take it easy John this is just a sharp scalpel. It will not cut deep so don't worry.
Me-I'm not John
Doc-I know, I am!
