Nothing. We focus more on social studies, religion, that kind of thing at this age (6 years). For the past 6 weeks one of our homeschooling groups have done cultural sharing. This is our homeschoolers of color group so it's a very diverse group with many folks being 1st and 2nd gen Americans, some immigrants, some adoptees, etc. So, they traveled to Mexico, Guatemala, Ghana, Portugal, Puerto Rico, Ethiopia, China, Japan, and a bunch more that I'm totally forgetting (DH attends with her, not me.. I work full time.)
We recently read some about Eid and fasting to help DD understand some of her uncle/aunt/cousins recent pictures on Facebook. We had a discussion about Jesus's childhood after looking at some art by Murillo. We had a discussion about Pagan religions after attending a Mabon gathering.
Basically, we are really focusing on exploring cultures with which she interacts regularly right now.
She has started to show some interest in ancient cultures, but much more from a scientific perspective. For example, we just had a chat about Salt the other day and I mentioned I knew about a book that told the history of Salt, and we decided we should get it. http://www.amazon.com/Story-Salt-Mar...6896401&sr=1-2
I know many people love SOTW and an official history curriculum, but that's just not for us.
