I am thinking about starting to teach people privately English in my little town. Figured i would put my teaching degree to use. Can anyone recommend a good series of English text books designed for German students?

It is a bit of a stretch to ask you guys but perhaps you know someone who is learning/learnt English.

Recomendations please!

Hi,
what we had in school was the "English G" series from Cornelsen. It has everything; little stories about english culture (UK & USA), grammar, exercises, jokes, vocabulary. What annoyed me was that any famous brand names were avoided, so they created stupid similar-sounding names. And they explained the difference between british and american English, which didn't help, but only confuse me...
In general, I think these are good books.

Don't take any books designed for the cambridge certificates FCE, CAE, CPE (unless thats the goal), because these textbooks really only focus on how to score in the exam.
