Educating the British

So tomorrow I have my first day as a teacher in the UK! I'm very excited about it and am geared up for the first day.I have my lesson plans done, and my games planned out and I am ready to roll. I've tried to think of all the little 'Canadian-isms' that might sneak into my vocabulary which might cause the children to react. For example; in Canada, we wear pants while Brits wear trousers. No big deal right? Wrong. Brits also wear pants...under their trousers! I wouldn't want to ask the kids to make sure they wear comfortable pants to class! Other ones that might come up are soccer/football, sweater/jumper. I need to be careful. Beyond that, I'm excited to be the new "foreign" teacher. I don't know what to expect from the kids... are they going to be really good? Because, obviously, if you live in London you must be entrenched in musical theatre trivia from birth right? They're going to catch on that I don't know anything about musicals written after Wicked. I think that a field trip to the West End is in order for me! I need to catch up on the current hits and find out who is who on stage today... so that I can talk about it to the kiddies. Best of all, it will be a business expense!
