Sites I use to make my own "textbook"

This summer, I'm doing an internship preparation program for students who will be working in the USA.  I was given total freedom to teach whatever I wanted to teach, based on whatever book I wanted to use.  I chose not to use a textbook, for reasons I explained in my last post.  Instead, I compiled my own book, using the following sites:

1. ESL Writing.  I particularly like the listening stuff.

2. Breaking News English.  I mostly use the 2-page "mini-lessons."

3. Film English. Fabulous lesson plans based on short videos to be found here.

4. Business English Pod. This is my go-to site for everything job interviews.

5. My own lesson plans that I've used for various classes.  Examples:  Renewable Energy,  South Korea's Education System, and Problems with Studying Abroad.
