    He was such a daydreamer that people called him a blockhead.When Leonardo grew up and traveled the world, he was inspired by the numbers used in different countries. Then he realized that many things in nature, from the number of petals on a flower to the spiral of a nautilus shell, seem to follow a certain pattern. The boy who was once teased for being a blockhead had discovered what came to be known as the Fibonacci Sequence!

     In MATH WITH BAD DRAWINGS, Ben Orlin answers math's three big questions: Why do I need to learn this? When am I ever going to use it? Why is it so hard? The answers come in various forms-cartoons, drawings, jokes, and the stories and insights of an empathetic teacher who believes that math should belong to everyone.Eschewing the tired old curriculum that begins in the wading pool of addition and subtraction and progresses to the shark infested waters of calculus (AKA the Great Weed Out Course), Orlin instead shows us how to think like a mathematician by teaching us a new game of Tic-Tac-Toe, how to understand an economic crisis by rolling a pair of dice, and the mathematical reason why you should never buy a second lottery ticket. Every example in the book is illustrated with his trademark "bad drawings," which convey both his humor and his message with perfect pitch and clarity. Organized by unconventional but compelling topics such as "Statistics: The Fine Art of Honest Lying," "Design: The Geometry of Stuff That Works," and "Probability: The Mathematics of Maybe," MATH WITH BAD DRAWINGS is a perfect read for fans of illustrated popular science.

    Seuss's classic treatise on the importance of a balanced life with our Anniversary Edition featuring cover art from the book's original publication! A Seussian spin on a conventional fairy tale, The King's Stilts is as topical today as when it was first published in 1939. It's the story of a devoted king who works hard and plays hard—and whose entire kingdom is threatened when his beloved stilts are stolen and he is too distraught to do his job.Written in prose instead of rhyme (unlike Seuss's later works), The King's Stilts nevertheless addresses subjects that we know Dr. Seuss was passionate about throughout his life: duty (as in Horton Hears a Who and Horton Hatches the Egg); the abuse of power (as in The 500 Hats of Bartholomew Cubbins and Yertle the Turtle); deceit (as in The Bippolo Seed and How the Grinch Stole Christmas)—and even cats (as in The Cat in the Hat and I Can Lick 30 Tigers Today)! A perfect way to introduce new readers to an old classic, or to reward existing fans with a collectible new edition. Follow the Good Doctor's advice: After a hard day of work, have fun with a great book like The King's Stilts!
