Well, I liked it better than Five in a Row, which isn't exactly setting the bar high, since I'm not a fan of FIAR. I also liked it better than Peggy Kaye's book tying lit. with activities (I forget the name of the book...Peggy Kaye wrote Games for Math, Games for Writing, etc.).
I decided to opt for slothdom, though, and simply read my kids the books without doing many activities. I guess I'm just not a literature-plus-activities sort of person.
