I had a look at this site after seeing it recommended here on Diigo (thanks!) and it seems to have a lot of potential.  I agree with Richard that teachers would probably need to adapt some of the activities. There are some nice materials though and the 'Rights & Responsibilities' and 'The Right to an Education' are a nice lead-in to the topic of human right as they use the familiar topic of school to get students thinking.

This is a ready-made lesson by Sean Banville about International Mine Day. It is quite accessible and there are different ways to use the material. I liked it because in addition to the reading / speaking / vocab activities it comes with an MP3 recording. Lots of potential!

Great for anyone who teaches Academic English or if you are studying yourself. Lots of info on writing conventions.

Very up to date ready-made reading, vocabulary and speaking activities. There is lots of material in each document so you probably won't have time / want to use it all. It's best to be selective! There are sometimes typos so it's important to check beforehand but it's an excellent source.

This is a fantastic site for lesson plans, activities and teacher training. Very high quality materials and lots of ideas.
