Technology is taking over our lives and using technology to learn English is no exception. Download ESL has lots of materials that you can use in your ESL or EFL classroom.
While the majority of the materials on their site are not free, they do have a couple of things you can try before you buy. There are two free sections: Power Point and Quizzes. I haven't bought any of their items, so I can't comment on the material they offer for a fee. However, you can try the free stuff and ask your school to purchase the rest.
