    The history of the Great Plains and the Santa Fe Trail is told in text and pictures by focusing on a cottonwood tree and the events that happen around it.

    Against the backdrop of Archimedes's life and culture, the author discusses the man's work, his discoveries and the knowledge later based upon it. The simple, often humorous, illustrations and diagrams greatly enhance the text. Ages 10 and up.

    Inside this book, families will find fun, mischief-making math problems to tackle—math that isn't just kid-friendly, but actually kid-appealing. With over 100 math riddles on topics from jalapeños and submarines to roller coasters and flamingos, this book bursts with math that looks nothing like school. And with three different levels of challenge (wee ones, little kids, and big kids), there's something for everyone. We can make numbers fun, and change the world, one Bedtime Math puzzle at a time.

    Puzzlists need only an elementary knowledge of math and a will to resist looking up the answer before trying to solve a problem.Written in a light and witty style, Entertaining Mathematical Puzzles is a mixture of old and new riddles, grouped into sections that cover a variety of mathematical topics: money, speed, plane and solid geometry, probability, topology, tricky puzzles, and more. The probability section, for example, points out that everything we do, everything that happens around us, obeys the laws of probability; geometry puzzles test our ability to think pictorially and often, in more than one dimension; while topology, among the "youngest and rowdiest branches of modern geometry," offers a glimpse into a strange dimension where properties remain unchanged, no matter how a figure is twisted, stretched, or compressed.Clear and concise comments at the beginning of each section explain the nature and importance of the math needed to solve each puzzle. A carefully explained solution follows each problem. In many cases, all that is needed to solve a puzzle is the ability to think logically and clearly, to be "on the alert for surprising, off-beat angles...that strange hidden factor that everyone else had overlooked."Fully illustrated, this engaging collection will appeal to parents and children, amateur mathematicians, scientists, and students alike, and may, as the author writes, make the reader "want to study the subject in earnest" and explains "some of the inviting paths that wind away from the problems into lusher areas of the mathematical jungle." 65 black-and-white illustrations.

    As a punishment, they're sent to their grandfather's house, where there's no TV and they have to do chores. And Grandpa is less tolerant of the twins' constant bickering.

However, when the cats learned of Spike’s team’s intentions, they went straight into action. These animals would not take that title from the cats, especially not a dog!In “The Fight for Best Pet,” Spike along with his friends, Doug the Golden Retriever, Tweet the yellow Warbler, Charlee the Hamster, and the other various animals, attempt to show the humans that they’re the best.

    Katherine Johnson was one of these mathematicians who used trajectories and complex equations to chart the space program. Even as Virginia’s Jim Crow laws were in place in the early 1950s, Katherine worked analyzing data at the NACA (later NASA) Langley laboratory. In 1962, as NASA prepared for the orbital mission of John Glenn, Katherine Johnson was called upon and John Glenn said “get the girl” (Katherine Johnson) to run the numbers by hand to chart the complexity of the orbital flight. He knew that his flight couldn’t work without her unique skills. President Barack Obama awarded Katherine Johnson the Presidential Medal of Freedom in 2015 and her incredible life inspired the Oscar-nominated film Hidden Figures. Get to know this incredible and inspirational woman with this beautifully illustrated picture book from an award-winning duo.
