I found this South America geography reader at Google books, and we have been reading it aloud in the evenings. It's general enough to still be relevant even though it is a vintage reader. It's also complementing our Rod & Staff Social Studies book, Understanding Latin America. We were reading about Cacao tonight which just happens to be in tomorrow's lesson about the lowlands. Nice pictures and maps throughout as well.
I especially liked the way they touched upon the differences of customs between the United States and Latin America with a wry sense of humor, pointing out that each of us could learn from each other. Subtle character lessons and the importance of learning about the world around us are transmitted which is always a nice bonus in a children's textbook.
