I recently spent some time exploring the website of The Metropolitan Museum of Art and found that there are some great resources for teachers and students on it. The first place that teachers will want to check out is the Publications for Educators page. In the Publications for Educators you will find a series of PDFs to accompany online features about the art of Egypt, Europe, Africa, and Asia.
Beyond the online features in the educators' section, there are some great activities that students can learn from on their own. Students might enjoy and learn from How Van Gogh Made His Mark. How Van Gogh Made His Mark is part biography, part art lesson, and part hands-on drawing activity. After reading about Van Gogh and seeing his art students can try their hands at creating their own Van Gogh-like drawings.
Students will also like Marduk, King of the Gods which is a narrated thirty slide presentation about ancient Mesopotamia.
