OCR Nationals Unit 2 - trying to make ICT interesting

I'm teaching OCR Nationals this year - a new challenge for myself as while I taught a single module of the curriculum on my first placement as a teacher, it's a whole new challenge when working full-time.

The group are an interesting bunch of pupils so I'll be aiming to keeping the pupils occupied much of the time.

One thing I do remember is to not bore people to death with Powerpoint slides - I think 9 for a full class is sufficient?

As regards making a class challenging so that the pupils don't even realize they're doing work, what's your advice? all comments welcome!
