Book excerpt: In this exciting new installment in the Flat Stanley’s Worldwide Adventure series, the Lambchop family is off to Boston, Massachusetts, for a little history and a whole lot of fun. And for parents and teachers, each Flat Stanley book is aligned to the Common Core State Standards, like multicultural adventure, plot and character development story elements, and compare and contrast. When the Lambchop family gets to Boston, Stanley is excited to go on a Duck Tour, eat lunch at Quincy Market, and see Fenway Park baseball stadium. Stanley even gets to be in a reenactment of American Colonist Paul Revere’s famous midnight ride. But Stanley has a problem. The Lambchops’ friend, Dr. Dan, is in town, too, and he’s giving a speech about his cure for flatness. And he wants Stanley to talk about being flat! But does Stanley want to change and be a regular kid, or would it be better to stay flat after all?
