That all depends on how much record-keeping your state requires. For Georgia, I keep all the written "academic" handwork my children do in a 3-ring binder for each girl. That's their "portfolio," so to speak. I also keep a journal on the computer detailing what we do every day (so that our oral work is accounted for). I start a new journal file every month. I include things that aren't necessarily "academic," but that I consider homeschooling. That way, all my bases are covered in the unlikely event that we are ever challenged. Georgia also requires that we send in a monthly attendance report. I just check off all the days we *didn't* homeschool that month, tally up the number of days homeschooled so far that year, copy it for my records, and mail it to the superintendent's office. The only other thing our state requires is standardized testing every third year (same as for public schooled students). We do this through our co-op. That way, my kids don't have to test among strangers.
