I've been spending time reading various ESL tutoring books that are available at my public library, in their ESL collection. I have been impressed with a few of them:
Real Basics by S E Treadgold is just as its title suggests, extremely basic. Every time I find a book that I think I will use over and over, my first impulse is to purchase it, but I resisted. The library has it, and unless I can find a used copy for a penny, as I was able to do with the 7th edition of Tutor, I'm going to resist the urge. This looks like a book any ESL tutor can use. It's heavily illustrated.
Teaching Adults, An ESL Resource Book, Developed by ProLiteracy America (ISBN 9781564201300) harkens back to my training classes. It expands on various teaching techniques for cultivating oral and written skills. Although the slant is for working with a class, the concepts are easily modified for one on one tutoring.
From Sound To Sentence, by Raymond C. Clark ( ISBN 9780866472517) looks like a wonderful resource. It is accompanied by 3 audio CDs. It's phonics based, with heavy emphasis on subtle differences in sound and the meaning of similar words. There are look, listen, say exercises as well as writing and numeric ones. This is a book that can be employed at various stages of a learner's progress.
