Hello,
I like “The Old Schoolhouse” magazine and as a matter of fact, their summer issue is all about Charlotte Mason style homeschooling. I am sure if you’re not a subscriber, and you were to subscribe now, that would be the issue to start out with! Also, they have an online version you can order too. Another one is the “Parents Review” which is actually a newsletter that Charlotte Mason started that you can order off of Karen Andreola’s site, which is, http://www.homeschoolhighlights.com I think. They have their other websites listed if that’s not the one!
So, I do LOVE Birds and Blooms as Heather mentioned for Nature Study as well!
