I actually liked the fact tracker more than I liked the book it was supposed to accompany. My five year-old daughter and I took turns reading the books to each other, she from The Knight at Dawn, me from the fact tracker. This method worked fairly well as both books have 10 chapters, but would have been better if the chapters in the fact tracker were arranged slightly differently. It seems like it wouldn't have been that difficult to sync up the two.
Overall, I felt the information was laid out in a logical manner, and while somewhat difficult for a five year-old, made a good attempt at explaining complex concepts in a simple manner.
