I am creating a site you and your students might enjoy and perhaps add to.
ahaafoundation.org is an online course in the history of art around the world. You can jump in anywhere. I would love to find a history teacher who would collaborate with me. My thought is to follow along with the book you are using and add the great art. You will see Pages for special requests under a rainbow where you can see how I have answered some of the request.

I would also like to hear historians review what has been created so far.

I love it and now how are you planning to start this project?
Catal Hoyuk and Harappa have some good information and images of the archeologists working there.

This information can also be found at ahaafoundation.org

Aloha to Queensland, David. I could work with you in a couple of ways. First I have to explain that I am no longer teaching in the classroom. I now spend the time working on the website and have been creating keynote slide shows from the work on the site to use for lectures here in Honolulu. The web site is a stand alone course which can be used entirely out of class. So far I have covered prehistoric art around the world and Early Villages 5,000 BCE and am working on Early Civilizations and have online India, Egypt, Mesopotamia and Crete. I am still working on those sites as I fiddle with the idea of a time frame.

It depends what time frame you cover as to how useful the site will be for each teacher. If I were a history teacher I would pose the question What does the art of this time tell you about the people and what do the people tell you about the time? In the early parts I would ask about what the architecture tells you about everyday living and when we get to the building of cities the students might be asked to talk about the meanings of monumental architecture.

The other thing I could do is to know from you what era you are teaching and create a page for your class on my site where I just gather the art and architecture of the time and give no detail. I wrote to someone who is teaching 20C Germany. The paintings of that time are amazing in what they have to say about the people. When asked I will collect the pictures and create a place and pages for that era. These students could then write a major piece using the images as part of a paper where they discuss the painter and what effect the times had on what was painted.

Does any of this work for you?
I am definitely open to discussion!!
