    And, it's true, many of them do. But Paul Erdos never followed the usual path. At the age of four, he could ask you when you were born and then calculate the number of seconds you had been alive in his head. But he didn't learn to butter his own bread until he turned twenty. Instead, he traveled around the world, from one mathematician to the next, collaborating on an astonishing number of publications. With a simple, lyrical text and richly layered illustrations, this is a beautiful introduction to the world of math and a fascinating look at the unique character traits that made "Uncle Paul" a great man.

    Frizzle's class is learning all about water. And when Wanda suggests they take a trip to Waterland, Ms Frizzle gets that funny look in her eyes.

    Butterflies can't survive cold weather, so when winter comes, many butterflies fly to warmer places. They migrate. Woodchucks don't like cold weather either but they don't migrate; they hibernate. Woodchucks sleep in their dens all winter long. Read and find out how other animals cope with winter's worst weather. This is a Level One Let’s-Read-and-Find-Out Science title, which means the book explores more challenging concepts for children in the primary grades and supports the Common Core Learning Standards, Next Generation Science Standards, and the Science, Technology, Engineering, and Math (STEM) standards. Let’s-Read-and-Find-Out is the winner of the American Association for the Advancement of Science/Subaru Science Books & Films Prize for Outstanding Science Series.

    you could jump from home plate to first base in one mighty leap!If you lifted like an ant...you could lift a car!If you grew as much in your first nine months of life as you grew in the nine months before you were born...you would weigh more than 2 1/2 million elephants and would be taller than a mountain!Did you know that a frog can jump 20 times its body length? Or that an ant can lift 50 times its weight? Or that a baby's weight increases 3 1/2 billion times during the nine months before it is born?These are but a few of the outrageous ratios that will amaze everyone! Students and teachers alike will have hours of fun exploring these delightful comparisons -- and inventing endless others of their own!David Schwartz has written the book in simple statements. And with a stretch of his imagination, artist James Warhola takes off on these wacky "what if" situations as he literally depicts the super-humans that would exist if people had the same super qualities as animals. For more serious math buffs, the author provides pages at the back of the book with equations and scientific facts that show just how these wacky but fascinating ratios are measured. As with How Much Is a Million?, this is another math book with endless possibilities for involving and exciting math lessons. Teachers will love this as much as their students will!
