I guess you could say that I belong to the "relaxed home schooler" club, but I wouldn't buy curriculum or prepare a home school schedule for boys, especially boys, that are 5 and 6.
You can go to Barnes and Noble or Borders and buy some workbooks to help them with handwriting, phonics or math, or buy some of those fancy toys they have now that teach phonics and/or math.
But the main place I'd be hanging out is the library. Check out lots of books. Books to read to them, books for them to read, picture books to look at in the subjects of science or geography.
Then I'd put them in the car a couple days a week and we'd go on field trips and do fun stuff.
My sister and I homeschool and we've always waited till the "boys" were about 7 to start anything that is remotely structured.
All of them have done great in their studies, always scored high on tests, and haven't seemed to suffer in the least from the delayed start and I believe we've avoided alot of frustration by waiting till they were a little older to start formalized teaching.
I'm not advocating complete lack of scheduling, just not for kids as young as yours.
Later on we used Saxon Math, Abeka, Beautiful Feet, mixed and matched lots of curriculum. There's so much available that you'll have a great time picking and choosing.
But if you wait a year or two, you'll figure out your child's learning style, and then you can cater the curriculum to the child.
