To help children learn about other countries: the land, people, food, music, customs, etc. (Note: this is not necessarily a multicultural unit. Children should be reminded at all times that people are special, no matter what their background, race, or customs. This is more along the lines of a "Social Studies" unit).
I choose to pick four different countries from various parts of the world -- one for each week in March. When I repeat the unit in two years, I'll choose four different countries and so on, until I have files of pictures, crafts, and activities for 12 - 16 different countries.
This year's countries: India, Mexico, Scotland, Zaire.

*Do not underestimate the value of this resource. I asked my son's teacher if he would stop by and just show my children his sari when we studied India (they had just finished their unit on India). This teacher just lives two doors down from me. Instead, he loaned me the sari, a man's shirt, the India flag, some cookbooks, and a record album with Indian music on it!

Videos (such as National Geographic) which "take a tour" of that country. Children probably won't sit still for the whole thing, but you can watch it first and just show small parts that would be of interest.
Animated videos which are set in that country (the children can be exposed to some culture and language without even being aware of it!).
Beauty and the Beast -- France
The Jungle Book -- India
The Hunchback of Notre Dame -- France
Kidsongs Video: "I'd Like to Teach the World to Sing."
Videos about animals which are native to the chosen country.
