    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.

    The Queen has everything, everything except a bed.

    Is there enough time? You have 3 shirts and 2 pairs of pants. Can you make 1 good outfit? Then you start to wonder: Why does everything have to be such a problem? Why do 2 apples always have to be added to 5 oranges? Why do 4 kids always have to divide 12 marbles? Why can't you just keep 10 cookies without someone taking 3 away? Why? Because you're the victim of a Math Curse. That's why. But don't despair. This is one girl's story of how that curse can be broken.

    When she looks at herself, she just sees a hole right in her center. Every day she watches the other numbers line up to count: "1, 2, 3, 4, 5, 6, 7 . . . !" "Those numbers have value. That's why they count," she thinks. But how could a number worth nothing become something? Zero feels empty inside. She watches One having fun with the other numbers. One has bold strokes and squared corners. Zero is big and round with no corners at all. "If I were like One, then I can count too," she thinks. So she pushes and pulls, stretches and straightens, forces and flattens herself, but in the end she realizes that she can only be Zero. As budding young readers learn about numbers and counting, they are also introduced to accepting different body types, developing social skills and character, and learning what it means to find value in yourself and in others.

    Playful elves demonstrate how to divide apples into halves, thirds, fourths, and more. Young readers will also learn about varieties of apples, including Golden and Red Delicious, Granny Smiths, Cortlands, and even Asian Pears.
