Literature and geography recommendation

[JadeOrchidSong]

Has anyone used McDougal Littell Literature and McDougal Littell World Cultures and Geography books for middle school?

I would like some programs that my boys can do independently. I will do discussions with them when necessary, though.

What have you used that you enjoy and recommend?

Here is a link to the geography book.

Thanks!
