Any teaching ideas?

Hi there everybody.

I have been asked to teach a couple of classes and I am struggling to come up with ideas so I thought I would ask you wonderful people for help/advice.

One class is about the characteristcs of British English and the other is about differences between British/American English. Like I said I have had a few ideas but now I am struggling to come up with anything else.

If you have any ideas that I would love to hear them!
