How can you tell Jax is uber-bored today? :P
Here're some really useful ESL websites I've found:
http://www.nclrc.org/essentials - Some of the more theoretical aspects of language teaching.
http://www.eigozai.com - Most of this page is in Japanese, but I just ran it through Google translator, and most of it was understandable. Has lessons and sound clips.
http://www.usingenglish.com - Really, really useful page. Has a glossary of grammatical terms (how many of you know what an "inchoative verb" is?), quizzes, handouts, etc, etc
http://www.englishclub.com - One of the most useful sites I've found. Has loads of games and stuff for the kids to play.
http://www.eslpod.com - One for the kids, perhaps. I'm putting a link of it onto my notice board, in case any of them feel super-motivated or something (wishful thinking, I know!!). Downloadable podcasts of English lessons.
