Hello there,
Yes I agree with the previous post. Don't panic at least you HAVE books you can follow. The people who put those books together do it with a lot of thought and they are a curriculum in themselves.
You can liven up the course books by adding in your own things when you have a chance. I'm very keen on using games in class and you can sign up to receive some free ones on
www.teachingenglishgames.com to try out.
I'd also add in, if you can, such things as a film library where the children can borrow DVDs or videos - you can buy them really cheaply second hand. They can take these and watch them at home, or perhaps after school if there is a facility for children waiting to be picked up. You can also have a few great cartoon books and amusing books such as books of sketches with amusing captions in the library too. Now most children will ignore these resources, but at least you have something in place for the keen and talented ones who do want to get ahead.
Kind regards
Shelley
