Hi,
Sounds like you might have some time.
Like every proffessional dance company, yours probably tapes everything and if you can get permission from your company to borrow a tape, I would bring it and let the students call the show off the TV. Talk about what you look for, dance terms, the importance of timing, why you do your cues a certain way (whether it's score, cue sheets, dance sheets, or whatever...).
Something I did in college (many moons ago) and found very helpful.
My two cents,
Have Fun!
