Hi there Echoe09
I have a fab. one to one teaching resource for private tutors and parents.
It consists of 140 games adapted for one to one use and 2 hours plus of video demos - those vids are mainly to show parents how to go about it.
The only snag is that it's for children aged 4 to 12 - level Beginner.
So many of the games won't really correspond to teaching an adult, though they are all good for teaching beginners.
The best thing I can suggest is that you watch the demo video on the site because it could give you some ideas - I'm sure it will.

PS When I write a book for adults I'll let you know! (but don't hold your breath).
