This is the last one I'm doing this year. Takes too much work, and I don't have anyone in any other grades right now!
Fourth Grade, Caleb style, can be accessed here: http://docs.google.com/View?id=ddssdqrh_15752xgxhg9
It's heavy on the History, drawing from a college-level US History course, because Caleb loves history. It's light on the math because we're using Saxon Math 54 this year because I trust Saxon and because Caleb can't stand to do a whole worksheet all of one kind of problem--drives him nuts with boredom.
I'm still polishing it up and fixing a few broken links, but most of it is accessible right away.
