    But what if we took these big, hard-to-imagine objects and events and compared them to things we can see, feel and touch? Instantly, we'd see our world in a whole new way." So begins this endlessly intriguing guide to better understanding all those really big ideas and numbers children come across on a regular basis. Author David J. Smith has found clever devices to scale down everything from time lines (the history of Earth compressed into one year), to quantities (all the wealth in the world divided into one hundred coins), to size differences (the planets shown as different types of balls). Accompanying each description is a kid-friendly drawing by illustrator Steve Adams that visually reinforces the concept. By simply reducing everything to human scale, Smith has made the incomprehensible easier to grasp, and therefore more meaningful. The children who just love these kinds of fact-filled, knock-your-socks-off books will want to read this one from cover to cover. It will find the most use, however, as an excellent classroom reference that can be reached for again and again when studying scale and measurement in math, and also for any number of applications in social studies, science and language arts. For those who want to delve a little deeper, Smith has included six suggestions for classroom projects. There is also a full page of resource information at the back of the book.

    . . nothing. But then . . . BANG! Stars caught fire and burned so long that they exploded, flinging stardust everywhere. And the ash of those stars turned into planets. Into our Earth. And into us. In a poetic text, Marion Dane Bauer takes readers from the trillionth of a second when our universe was born to the singularities that became each one of us, while vivid illustrations by Ekua Holmes capture the void before the Big Bang and the ensuing life that burst across galaxies. A seamless blend of science and art, this picture book reveals the composition of our world and beyond -- and how we are all the stuff of stars.

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.
