Here is the first of the Raven Open (Source) English materials... and below you can get a bit of an introduction to the idea as well as some suggestions on ways to use it.
Here are the free downloads for this material:
Open English: Picket Fence (MS Word 2007)
Open English: Picket Fence (Compatible)
Remember that it's all open source material ('share alike'), though if you do change and/or add stuff, I'd love to hear from you and learn from what you did.
Enjoy your open sauce (more on the way next Thursday...)!
