If You're So Smart, How Come You Can't Spell Mississippi? by Barbara Esham Illustrated by Mike and Carl Gordon

 

After discovering that her father is dyslexic and was not always the smartest little boy in school, a little girl goes on an information exploration about dyslexia and people throughout history who have overcome difficulties with it. I think this book does a really good job of laying out the before and after thoughts of the little girl as she realized that her father was not always the smart and successful person that he is now.
