It's a book. I was a best seller in the IRA catalog. I'm a reading specialist/literacy coach and purchased it along with several other recommended books. You can read more about it on amazon.com and/or IRAs website. I purchased with the hope/thought that it might offer a fresh take on a "structure" for guided practice with struggling readers. Still familiarizing myself with it which is why I'd like to hear from anyone who might have used it
I'm happy to share more as I learn more.
