IED 6 - INVADER
If you'd like to set up a game of INVADER with your students, I've written an article outlining the logistics and suggesting some of the language areas you might use it to focus on. Check out pages 17-20 of The British Council's In English Digital magazine or download a pdf of the article directly.
For the curious, I've been asked several times whether the binary code on the front cover of the magazine is randomly generated or actually means something. The answer is… that you'll have to type it into a binary to ASCII converter and find out! :)
