Over the course of the past few weeks we've read a fiction book on the Mayans (The Corn Grows Ripe) and another on the Incans (Secrets of the Andes). We've watched short animated movies through Brain Pop and did vocabulary, geography and tests through there as well.
We watched Cracking the Mayan Code, a PBS movie through NetFlix streaming, last week. Then we read the DK Aztecs non-fiction book and discussed all the things we've learned about them and the Conquistadors. We also read Amazing Mayan Inventions and made drawings of our own inventions. I printed out things through Enchanted Learning for some Mexico worksheets including coloring the Mexico flag.
With our heads swimming with codices, step pyramids and gold we rounded out our studies with a hands-on project: Geosafari's Mayan Dig.
I found this on clearance at my local Lakeshore Learning. Even not on sale it's a fairly good price. It comes with a very comprehensive booklet with math problems and little worksheets for the artifacts you find. You could really do a fairly complete lesson just with this kit. There is a little scraper and paint brush and a clay brick. Alex has been anxious to do this for awhile.
It's a lot more work than you'd think, scraping away slivers of clay while trying to find the four artifacts hidden within. He held his own for a good bit.
