looking for 'ER diagram' examples

I'm currently taking a database systems class in Chicago, IL and am having trouble understanding ER diagrams - the topic currently being taught. Unfortunately, the book does not provide many examples for how to construct an ER diagram. Does anyone know of any good reference material on ER digrams with plenty of examples and problems w/ answer key in back of book. I think I need to practice constructing many diagrams before I can gain a good understanding of how they work.

Any help would be greatly appreciated! I have a midterm on the material coming up at the end of this week.
