For our schooling, we use literature based unit studies. This means we take a book to read (or sometimes a theme) and connect virtually all of our learning to that particular book/theme . It's been great for us because it offers a connection and application to what we're learning. (Yes, I'm learning a ton too!)
Literature based unit studies can be purchased in many different places, but there is one website where you can get them for free!! HomeschoolShare.com is a site that offers free unit studies written by home schoolers who want to share their ideas. "Many minds make light work" is their slogan. So, be one of those many minds and share your ideas! They have a blast each year during which many units are submitted. This years blast is coming up, so click on the rocket and check it out!
