There is beautiful mathematics in the natural world. In this book a child takes a spring math walk in search of interesting treasures. Colourful photos and an easy to access text invite both children and adults to explore the wonders of the spring world. This book can spark mathematical conversations with children, and be used as a guide for discovering the rich math that exists in nature. Photos can also be used to engage children in math talks as they observe and discuss what they see. Mathematical facts for each photo are provided at the end of the book that can be used to prompt readers in learning more about how math shapes our natural world.

There are two kinds of math: the hard kind and the easy kind. The easy kind, practiced by ants, shrimp, Welsh corgis -- and us -- is innate. What innate calculating skills do we humans have? Leaving aside built-in mathematics, such as the visual system, ordinary people do just fine when faced with mathematical tasks in the course of the day. Yet when they are confronted with the same tasks presented as "math," their accuracy often drops. But if we have innate mathematical ability, why do we have to teach math and why do most of us find it so hard to learn? Are there tricks or strategies that the ordinary person can do to improve mathematical ability? Can we improve our math skills by learning from dogs, cats, and other creatures that "do math"? The answer to each of these questions is a qualified yes. All these examples of animal math suggest that if we want to do better in the formal kind of math, we should see how it arises from natural mathematics. From NPR's "Math Guy" -- The Math Instinct will provide even the most number-phobic among us with confidence in our own mathematical abilities.

The first chapter of this book traces the history of the development of walking machines from the original ideas of man-amplifiers and military rough-ground transport to today's diverse academic and industrial research and development projects. It concludes with a brief account of research on other unusual methods of locomotion. The heart of the book is the next three chapters on the theory and engineering of legged robots. Chapter 2 presents the basics of land loco motion, going on to consider the energetics of legged movement and the description and classification of gaits. Chapter 3, dealing with the mechanics of legged vehicles, goes into leg number and arrangement, and discusses mechanical design and actuation methods. Chapter 4 deals with analysis and control, describing the aims of control theory and the methods of modelling and control which have been used for both highly dynamic robots and multi-legged machines. Having dealt with the theory of control it is necessary to discuss the computing system on which control is to be implemented. This is done in Chapter 5, which covers architectures, sensing, algorithms and pro gramming languages. Chapter 6 brings together the threads of the theory and engineering discussed in earlier chapters and summarizes the current walking machine research projects. Finally, the applications, both actual and potential, of legged locomotion are described. Introduction Research into legged machines is expanding rapidly. There are several reasons why this is happening at this particular time.

Tell me your secrets, and I'll tell you mine... Schoolteacher Sienna Cruz has always been a good girl. She’s a dreamer, a rule-follower, and she’s saving herself for marriage. She’s also just won a coveted position teaching in a prestigious London school, which means in a few short months she’ll be saying goodbye to Whispering Pines forever. Everything is going according to plan until she meets playboy Dashiell Springer. Dash has made too many mistakes to count. He dropped out of high school and hitch-hiked his way across the country. He met the wrong woman, ran with the wrong crowd, and ended up with a prison record. After eight years on the West Coast, coming home to open a local gym is his first step toward a fresh start. He has no intention of revealing his past or starting up a relationship with anyone, let alone a woman like Sienna who’s way out of his league. But the more time they spend together, the more both Sienna and Dash begin to question everything about the rules of dating they’ve set for themselves. When Dash’s past catches up with him, will their relationship be strong enough to withstand the truth? If you love small towns, memorable characters, and swoon-worthy happy endings, then you'll love this sweet romance by a USA Today best-selling author!

This book builds on the Teachers Empowered to Advance Change in Mathematics (TEACH Math) project, which was an initiative that sought to develop a new generation of preK-8 mathematics teachers to connect mathematics, children’s mathematical thinking, and community and family knowledge in mathematics instruction – or what we have come to call children’s multiple mathematical knowledge bases in mathematics instruction, with an explicit focus on equity. Much of the work involved in the TEACH Math project included the development of three instructional modules for preK-8 mathematics methods courses to support the project’s goals. These activities were used and refined over eight semesters, and in Fall 2014 shared at a dissemination conference with other mathematics teacher educators from a variety of universities across the United States. Chapter contributions represent diverse program and geographical contexts and teach prospective and practicing teachers from a variety of socioeconomic and ethnic backgrounds, in particular providing accounts of supports, challenges, and tensions in implementing equity-based mathematics teacher education. The chapters supply rich evidence and illustrative examples of how other mathematics teacher educators and professional developers might make the modules work for their unique practices, courses, workshops, and prospective teachers/teachers. It promises to be an important resource for offering guidance and examples to those working with prospective teachers of mathematics who want to create positive, culturally responsive, and equity-based mathematics experiences for our nation’s youth.

When a single act of indiscretion places smart and responsible teen Breanna in the path of a cyberbully, she finds unexpected protection from motorcycle gang member Razor, who asks for her help in finding answers to a longstanding mystery.

Brandon Hanson and Katie Parker both grew up in Greeneville, North Carolina. They both went to the same schools, but more importantly, they both possessed a will to survive. Brandon had some tough decisions to make about family problems, love, and ultimately enlisting in the Vietnam War. Katie had a supportive family, a steady young love, and a successful childhood. The two were destined to meetthe question would be when. After they got to know each other, the decision for Brandon became whether or not to go to college or the war in Vietnam. He only had months to decideknowing his decision would affect a lot of people in his life. Join Brandon and Katie on a journey of betrayal, heartache, lust, and love by taking A Walk in the Past.
