Do you have any ideas on books to use and lessons to do for the following situation: I will teach ESL classes at a factory, all students are Latinos, level 2 and level 3 students. The company has a preference that I focus on speaking skills and that I make sure to include English that is relevant to a factory/production type of workplace (in addition to English in general).

get another career.....teaching in California is the vortex of ineptitude

The site that helped me most was this site. It had a lot of what I needed to teach without having to do too much extra work.
Teaching ESL is probably one of the most rewarding classes you will have. Make it fun and interesting and your students will learn quickly.
