Lincoln's legacy is everywhere - there he is on your penny and five-dollar bill. And we are still the United States because Lincoln helped hold them together. But who was he, really? The little girl in this book wants to find out. Among the many other things, she discovers our sixteenth president was a man who believed in freedom for all, had a dog named Fido, loved Mozart, apples, and his wife's vanilla cake, and kept his notes in his hat. From his boyhood in a log cabin to his famous presidency and untimely death, Kalman shares Lincoln's remarkable life with young readers in a fresh and exciting way.

    Julia Diggins masterfully recreates the atmosphere of ancient times, when men, using three simple tools, the string, the straightedge, and the shadow, discovered the basic principles and constructions of elementary geometry. Her book reveals how these discoveries related to the early civilizations of Mesopotamia, Egypt, and Greece.The fabric of the story is woven out of archeological and historical records and legends about the major men of mathematics. By reconstructing the events as they might have happened, Diggins enables the attentive reader to easily follow the pattern of reasoning that leads to an ingenious proof of the Pythagorean theorem, an appreciation of the significance of the Golden Mean in art and architecture, and the construction of the five regular solids.Out of print for 34 years, Julia Diggins' classic book is back and is a must-read for middle school students or for parents helping their children through their first geometry course. You will be fascinated with the graphic illustrations and written depiction of how the knowledge and wisdom of so many cultures helped shape our civilization today. This book is popular with teachers and parents who use Jamie York's Making Math Meaningful curriculum books.
