I found this cool resource at our local Sam's club and am planning on adding it to our world geography studies for next year:
(It's not significantly cheaper there than the price I see on Amazon for it, however....)
It is by Dan Cowling.
I like the way this is set up! It comes with some Faber-Castell pencils, an eraser, and sharpener. The same publishers (Thunder Bay Press) have one on human anatomy that I thought about adding to our health class, too, but I really didn't like the way it was set up. It's not at all like the geography book....
