The Great Books Foundation has updated their free materials list. Go check out the list here, but hurry. They go pretty fast!
These materials are great for teachers, homeschoolers, or just anyone interested in giving their kids an extra boost. Ground shipping is free, and as long as your order totals zero (if you choose the free items/shipping it will) you don't even need to provide credit card information.
The current list includes items for elementary through high school!
What a fabulous resource!
