*Warning...I got a little ranty towards the end....
This was an extreme challenge for me to read as Geometry is my least favorite of the math subjects. Part of my reason for reading this was to find new and interesting ways to wrap my head around the concepts.
I did get some new ways to help with proofs. Using "if...thens" to create the links needed will help greatly when trying to teach proofs. I also came out with a better understanding of indirect proofs.
My struggle appeared probably a third of the way through this book. I know that this book is written for girls and that it is supposed to help with self esteem. However, as a 31 year old woman the examples, the illustrations, and doodles seemed to be a little shallow and overly girlie. What about the example for the tomboy, the young woman who isn't into boys, or a doodle of a girl who isn't stick thin with hips and boobs? I don't need a crown and wand to set apart the theorems. In previous books this never bothered me (as I didn't notice it) but now that my daughter, who's 3, is developing likes and dislikes, I want her to know that she doesn't have to live in a prissy, pink, glittery box (although I think she would love that kind of box, she'd probably want to bring in a bucket of dirt).
My last comment is Danica's goal is to show girls and the world that "math is sexy" and I'm not honestly sure that we need to make everything "sexy". Can't math and your competence at math be an expected quality like punctuality, cooperation, and general cleanliness?
