CNN: A lesson in finance - Teachers sell their original work online

For all those teachers who take work home at night, creating lessons they hope kids will like, the reward is a good day in class. Now there could be another payoff: cash.
Teachers are selling their original lectures, course outlines and study guides to other teachers through a new Web site launched by New York entrepreneur Paul Edelman.
The site, TeachersPayTeachers.com, aims to be an eBay for educators. For a $29.95 yearly fee, sellers can post their work and set their prices. Buyers rate the products.
