Some Good ESL Resources for Teachers

There`s a very good grammar eBook for free that I downloaded myself and so did one of our teachers.

http://www.how-to-teach-english-in-japan.com/public-domain-ebooks.html  Check out " Just Enough English Grammar."

I think it is good and it is free!

EFL 4U is good.  You probably know of that one already though.   Kurt makes materials for teachers in Japan.
Not free but worth the money in my opinion.
