Here's a neat site with some cool printables. I love these geography printables:
If I had to start all over at homeschooling day 1 knowing what I know now, I might've gone with My Father's World curriculum http://www.mfwbooks.com/ because it so well combines subjects and grade levels -all you add is math and language arts - everything else is the same for all age levels. It makes it very easy on you. I have a friend who has 4 kids 1-6th and Father's World makes it SO much easier for her. I have been so impressed with Abeka Math, spelling and language. I've always had cheap and easy access to Abeka stuff - financially it was a much better deal for us, and now at this point, I can keep passing down stuff I've used before to the next kid -it's just reasonable for me to stay with it. Plus, resources for geography, history, and science are so readily available through the library and computer for free -I just never could justify the expense.
Hope all that helps! Don't worry!
