Good deal. Then you might also get some milage out of my tutorial on the Circle of Fifths.

It definitely helps unlock a lot of ideas about including accidental as modulations. This is because modulating with the circle of 5ths is essentially a temporary change of key signature. It's a farily advanced topic, so I usually wait to introduce it until after students have the basics covered; intro to music theory, improv, all the stuff in the tutorials I linked above. :)
I agree, Lisa's tutorial on Chord Theory is very helpful!
Ask more if necessary. Have fun!
