Teaching Sibelius

I'm teaching a clinic to a high school AP music theory class on writing and engraving in Sibelius - it will be two sessions, one 50 minutes and one 90 minutes. Does anyone have any teaching resources/ideas for engaging a high school class with it? I'm thinking of making a general lesson plan of letting them compose something after a quick tutorial, and be there in the computer lab to answer questions. If they're not into that, I'll have some excerpts they can choose transcribe/arrange. I kind of want to make a handout with some shortcuts/basic functions, screenshots. Does anyone have a suitable resource? AFAIK, they have Sibelius 4 in the lab (since I have 6, I'm not going to get too specific because I don't know what details were added in later versions).

Thanks!

you will have to install the v.4, because is for sure that you'll need it, someone will make you a question or something and you won't feel completely sure if what you're saying is just the way you say.

Both version installed at the same time makes no problem to the system, just the .sib association maybe.

I know you handle the Sibelius very good and I assume you will be good teaching, just make them to use the keyboard would you, ... not everything with the mouse, that's slooooow. Good luck.
