This book was about a girl who is a math genius but also exhibits obsessive-compulsive behaviors. Because it's the 1930s, many (including her parents) don't think she should pursue her love of math. Her grandfather is her fiercest advocate and helps her on her journey. We had great discussions about "what girls can do and what boys can do" and how to pay attention when gender bias slips in-- it's tough because it's so built in to our culture in the United States. The girls were also floored that a movie only cost 10 cents in the 1930s!
