    . . and almost as many ways to measure them!Marvelosissimo the Mathematical Magician is back -- and ready to explore the invention of length, weight, and volume measurements. After that, with another wave of his wand, the wizard introduces the world of metrics and makes it easy to understand the basic pattern of meters, liters, and grams. With Steven Kellogg's playful and delightfully detailed illustrations, measuring has never been such a blast!

    A reward of one grain of rice doubles day by day into millions of grains of rice when a selfish raja is outwitted by a clever village girl.

    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.

    She has to use standard units like inches and nonstandard units like paper clips to find out height, width, length, weight, volume, temperature, and time. Lisa decides to measure her dog, Penny, and finds out ... Penny's nose = 1 inch long Penny's tail = 1 dog biscuit longPenny's paw print = 3 centimeters wide ... and that's only the beginning! Lisa learns a lot about her dog and about measuring, and even has fun doing it.This clear and engaging concept book, delivered with a sense of humor, is certain to win over the most reluctant mathematician.

    Children start to count long before they learn their ABC's, for they are constantly comparing and classifying things and events they observe around them. As they try to bring sense and order into what they observe, they are actually performing basic mathematical feats.In this book, Mitsumasa Anno, the creator of the brilliantly inventive Anno's Alphabet, invites young readers on another stimulating adventure of the imagination-this time into the world of numbers and counting. Gentle watercolor pictures show a landscape changing through the various times of day and the turning seasons, months and years, and the activities of the people and animals who come to live there. But the seemingly simple plan of the book is deceptive: look more carefully and you will see one-to-one correspondences; groups and sets; scales and tabulations; changes over time periods; and many other mathematical relationships as they occur in natural, everyday living. Just as our forebears developed our number system from observing the order of nature, the reader is subtly led to see and understand the real meaning of numbers.Look at this book and look again. Each time you do so, you will find another application of a natural mathematical concept that you had not noticed before.
