I signed Marissa up for an online writing class. I heard Julie Bogart (founder of Bravewriter) speak at one of our homeschool meetings; very good! Another friend of mine speaks highly of Bravewriter and the positive effects it has had on her sons. The website has many helpful ideas even without signing up for the classes. Here is a list of free articles that she offers.
One neat thing my friend told me is that the first class that Marissa is enrolled in (Kidswrite Basic) not only teaches the child how to write, but also teaches the mom how to teach the child to write. The other free service that she offers is a mom e-newsletter. If you sign up, you'll receive emails with ideas of how to implement her Braverwriter philosophy into your home.
