It always is nice when a professor takes the time to put together a course packet, but sometimes it can be frustrating when you don't understand something in class, and go to the course packet to find it explained the same way.
Internet to the rescue! Steal somebody else's course packet and direct your students to it. Maybe have a couple of course packets. Variety helps, and students these days are (or should be) good at ignoring vast amounts of irrelevant material.
