I just got my new CLE homeschool catalog, and was very happy to see that they now sell Victory Drill Book as a supplement to reading! I got this book long ago, when I read Rudolph Flesch's Why Johnny Can't Read (but you can teach him at home), or maybe it was Why Johnny Still Can't Read (but you can teach him at home). He highly recommended it, but then gave a sort of short-course on it within his own book. I dug out the book and I'm going to start it with dgs (as a supplement) today!
