I have been looking around online for free resources that are available to homeschoolers. Here are a couple of good sites that I found or that people have recommended.
http://www.amblesideonline.org/- This site has book lists and reading schedules that follow the Charlotte Mason approach to education.
http://www.thehomeschoolmom.com/ There is a lot of different things on her site regarding homeschooling and meal planning. There is also a list of freebies, some of the ones I clicked on were out of date though. You can sign up for a free newsletter and weekly favorite homeschooling site.
http://www.googolpower.com/ Free virtual field trips. This is pretty cool especially if you live in a place where you might not get to do a lot of fieldtrips in person. There are also free printables on this site. They also have a free newsletter you can sign up for.
http://www.notebookingpages.com/ This is my favorite so far. Notebooking is a great way to keep all of your child's stuff together and organized. It is also neat to look back on what they have learned over the years. It is also a great way to keep all of their projects. Every time we do a project, we take a picture of it to put in a notebook. That way you will always have the picture even if you can't keep the project. (If you have more than one child you know what I mean, the fridge can get awfully crowded) There are several articles on notebooking and free notebooking pages!
