My 8 year old has just entered year 2 of learning. He has a group lesson once a week. Mind you....he's been formally learning for a year. They progress from high E string down the line. He JUST started low E string a couple weeks ago, so understand that what's basic for us is a long process of practice, reading notes, practice......
Since my early learning became somewhat sour because of the lack of "cool songs" to play, I have started from the very beginning to give him fun stuff to play. Before he had ANY chords formally, I worked in the beginning riff to AC/DC's Back in Black. E D A and the little solo riff. He was very determined and learned that.
As he progressed, we continue to practice his formal lesson material about 15 minutes a day. (remember, he started when he was 7 and has a shorter attention span). When the formal lesson is satisfactorily done, then he's able to ask me to teach him any song he wants.....or he can do his own stuff. I've given him.....and he can do on his own....slowly....Linkin Park Bleed it Out, AC/DC Thunderstruck, and maybe 2 or 3 others that slip my mind now.
My 12 year old had an interest at first (was 10 at the time) and did NOT want formal lessons. I gave him the beginnings to Lynyrd Skynyrd Sweet Home Alabama. My strategy here was to keep the 2 of them on different songs so as to not have competition between them.
I do feel that the weekly lessons keeps him playing. He does pick up the guitar on his own (I can hear him playing his acoustic right now) but without the constant re-enforcement, it's easy for them to slack off.
Be the secondary teacher. Help with whatever the teacher gives him and give him some of the easy riffs that can go for 10 seconds. A friend (in his 30's) just took up guitar and I gave him (over email) the very beginning of the Rolling Stones....Dirty Water. Easiest riff ever, but anyone who hears it recognizes is.....even if they can't name the song. That's instant positive feedback for the player.
