What do you want?
The prestige of being an accredited professor, helping those who really want to learn, a resume bullet or two (had to mention that, please do not take it personally)? Something else?
If I were you, I'd go after the critical age (7th, 8th grade) where life changing learning experiences can happen. Reach out and contact technology teachers or math/science teachers who teach in those grades in your relative geographic area. Tell them you want to help teach - maybe an after school program, maybe private tutoring, leave it open.
I think by just getting out there and teaching you will burst some of the romantic notions of what you think teaching will be like and be left with the salient aspects.
Maybe you have a gift, maybe you will meet a future technical co-founder, good luck!
Don't get hung up on credentialing. And like another poster said - volunteer to give talks to peers who may be more experienced than you.
Be bold and ask people for help, give!
