We just did a unit on this.
It started with me giving The Kid a bunch of Confederate money after he picked the state he was from. He had to use that to pay for things around the home - meals, computer time, etc. We then did different things each day - reading the constitution so he could develop his argument for why he wanted to secede, tearing apart what his history book said (no slaves in the north, for example, or that they had no big farms to need slaves), following the Underground Railroad with the help of a book called The Safe House, and then playing soldier - eating what the soldiers ate, following the battles as they happened (drawing up lists of the dead and newspaper reports too), learning how to decode the Morse Code messages I left around the house (having them say things like "there's a piece of candy in the napkin drawer" kept the enthusiasm alive.

)...by the end of the week his confederate money was no good anymore, and we started learning how the South survived. We read the Hannalee books (Turn Homeward/Be Ever Faithful) to see what it was like from a child's perspective, being taken from her home and kidnapped as a war prisoner because she worked in the mills, then coming home to find Atlanta burned and the only man in the family returning injured.
There is a unit study/lapbook on Homeschoolshare.com that we loosely based ours on and I found that to be a great resource. I wish I had the money for
Jackdaws because those would have helped a bunch. Maybe when we get to it the second time..
