The background information is nice and concise. You can learn a little about each building and Wright's inspirations. It also lists other resources on Wright that are available. It further explores the relationship of Wright's architecture to the Victorian style.
One of my favorite parts is the list of vocabulary words and definitions. This is a great resources for any student studying architecture!
There is also a nice letter from Llewelyn Wright that is pretty interesting.
When my fourth graders were studying Frank Lloyd Wrights Art Glass, I found another very helpful packet online. You can read more about it in my earlier post.
