    There were so many things that he could do with all of that money! He could buy as much gum as he wanted, or even a walkie-talkie, if he saved enough. But somehow the money began to disappear... Readers of all ages will be delighted by this attractive new edition of Judith Viorst's beloved picture book.

    When the headmaster forces Minagi's entire class to study Einstein's theory of relativity over summer school, Minagi volunteers to go in their place. There's just one problem: He's never even heard of relativity before! Luckily, Minagi has the plucky Miss Uraga to teach him. Follow along with The Manga Guide to Relativity as Minagi learns about the non-intuitive laws that shape our universe. Before you know it, you'll master difficult concepts like inertial frames of reference, unified spacetime, and the equivalence principle. You'll see how relativity affects modern astronomy and discover why GPS systems and other everyday technologies depend on Einstein's extraordinary discovery. The Manga Guide to Relativity also teaches you how to: Understand and use E = mc2, the world's most famous equation Calculate the effects of time dilation using the Pythagorean theorem Understand classic thought experiments like the Twin Paradox, and see why length contracts and mass increases at relativistic speeds Grasp the underpinnings of Einstein's special and general theories of relativity If the idea of bending space and time really warps your brain, let The Manga Guide to Relativity straighten things out.

    And watch out for One Finger Jimmy, Chainsaw Charlie and their gangster friends, who are living proof that maths can be murderous.

    Beautifully illustrated with old engravings as well as contemporary imagery, Sacred Number introduces basic counting systems; significant numbers from major religious texts; the importance of astronomy, geometry, and music to number quality; how numbers affect architecture. Lundy explains why the ideas of Pythagoras still resonate, and she profiles each number from one to ten to show its distinct qualities: why, for example, the golden section is associated with five, and seven with the Virgin Mary.

    Each spread features an equation showing one way to add up to ten, while the acrobatic mice split into two groups representing the numbers in the sum. 9 mice tidy. 1 mouse somersaults. 9 + 1 = 10. Some mice mop and scrub, while others spin and clown around. 8 mice cook. 2 mice juggle. 8 + 2 = 10. Look out as they swing and tumble! 7 mice wash. 3 mice spin. 7 + 3 = 10. All the mice are busy as they act out different ways to make the same sum.

    Cases, datasets, and examples allow for a more real-world perspective and explore relevant uses of regression techniques in business today.

    Whenever they'd get the chance, they'd dance! She'd sing and snap. He'd tappity-tap. What a pair they made! At the end of each day, they'd always say, "ONE, TWO, I'll count on you, 'til the end, we'll be best friends." Until Three jumps in between them . . . Suddenly One only wants to play with Three. "ONE, THREE, odds we'll be!" they chant. Two feels left out. But what can she do? Another character-building counting book by award-winning author Kathryn Otoshi, Two is a powerful story of friendship, loss, letting go, and self-discovery.

     Building Thinking Classrooms in Mathematics, Grades K-12 helps teachers implement 14 optimal practices for thinking that create an ideal setting for deep mathematics learning to occur.

    Michael Guillen, known to millions as the science editor of ABC's Good Morning America, tells the fascinating stories behind five mathematical equations. As a regular contributor to daytime's most popular morning news show and an instructor at Harvard University, Dr. Michael Guillen has earned the respect of millions as a clear and entertaining guide to the exhilarating world of science and mathematics. Now Dr. Guillen unravels the equations that have led to the inventions and events that characterize the modern world, one of which -- Albert Einstein's famous energy equation, E=mc2 -- enabled the creation of the nuclear bomb. Also revealed are the mathematical foundations for the moon landing, airplane travel, the electric generator -- and even life itself. Praised by Publishers Weekly as "a wholly accessible, beautifully written exploration of the potent mathematical imagination," and named a Best Nonfiction Book of 1995, the stories behind The Five Equations That Changed the World, as told by Dr. Guillen, are not only chronicles of science, but also gripping dramas of jealousy, fame, war, and discovery. Dr. Michael Guillen is Instructor of Physics and Mathematics in the Core Curriculum Program at Harvard University.

    In Intentional Talk: How to Structure and Lead Productive Mathematical Discussions , authors Elham Kazemi and Allison Hintz provide teachers with a framework for planning and facilitating purposeful math talks that move group discussions to the next level while achieving a mathematical goal.Through detailed vignettes from both primary and upper elementary classrooms, the authors provide a window into how teachers lead discussions and make important pedagogical decisions along the way. By creating equitable opportunities to share ideas, teachers can orient students to one another while enforcing that all students are sense makers and their ideas are valued. They examine students’ roles as both listeners and talkers, offering numerous strategies for improving student participation. Intentional Talk includes a collection of lesson planning templates in the appendix to help teachers apply the right structure to discussions in their own classrooms.

    Two primary objectives guided the authors in the revision of this book: to develop precise, readable materials for students that clearly define and demonstrate concepts and rules of calculus; and to design comprehensive teaching resources for instructors that employ proven pedagogical techniques and save time. The Larson/Hostetler/Edwards Calculus program offers a solution to address the needs of any calculus course and any level of calculus student. Every edition from the first to the fourth of Calculus: Early Transcendental Functions, 4/e has made the mastery of traditional calculus skills a priority, while embracing the best features of new technology and, when appropriate, calculus reform ideas. Now, the Fourth Edition is part of the first calculus program to offer algorithmic homework and testing created in Maple so that answers can be evaluated with complete mathematical accuracy.

    Who ever heard of a peasant marrying a princess? But Pong Lo is wiser than the Emperor knows. And when he concocts a potion that saves the Princess's life, the Emperor gladly offers him any reward he chooses--except the Princess.   Pong Lo makes a surprising request. He asks for a single grain of rice, doubled every day for one hundred days. The baffled Emperor obliges--only to discover that if you're as clever as Pong Lo, you can turn a single grain of rice into all the wealth and happiness in the world! Praise for A Grain of Rice: "Clever and quietly told in simple, yet evocative language."-Kirkus Reviews"Pittman invites readers into her story through her choice of concrete objects, sensory images, and universal messages. She borrows from the motifs of oral literature, and also weaves in information about arithmetical progression and 15th-Century Chinese people, patterns, and traditions. Pittman's well executed pencil drawings ooze with emotion, and there is a fusion of text and illustrations...[A] book that is wise and humorous, and one to be perused and savored."-School Library Journal"Gracefully illustrated with finely shaded drawings, this picture book tells of Pong Lo, a poor Chinese peasant who wins the hand of the emperor's daughter through his knowledge of mathematical principles."-Booklist

    Is there enough time? You have 3 shirts and 2 pairs of pants. Can you make 1 good outfit? Then you start to wonder: Why does everything have to be such a problem? Why do 2 apples always have to be added to 5 oranges? Why do 4 kids always have to divide 12 marbles? Why can't you just keep 10 cookies without someone taking 3 away? Why? Because you're the victim of a Math Curse. That's why. But don't despair. This is one girl's story of how that curse can be broken.

    Stump your family, friends, or favorite enemy with these deceptively simple dares.
