Dad's Math Book Makes the Grade

Thanks to Joanne Jacobs for this interesting article about how an engineer, a native of Ghana and now living in Detroit, decided to give up his full-time job to dedicate himself to writing a series of math texts to help his own children (who were struggling) and now others. After reading the full article I must say I want to see more details and samples of what he's written. According to the article, his materials adhere to his state's standards and apparently blend the traditional algorithms and skill development with conceptual understanding. Gee, does this sound familiar! The fact that other parents and school administrators are now taking notice and want copies is fascinating. Textbook publishers pour tons of money into developing a new math series and along comes one individual who decided these materials were simply not working for his children. Is there a message here?
