Big numbers-- like millions, billions, and trillions-- are hard to imagine.  Whether it's a trillion pieces of popcorn, a billion dollars, or even bigger numbers, the concrete examples in Millions, Billions, & Trillions, laid out in simple, kid-friendly language and bright, cartoony illustrations, will help young readers make sense of large values and develop a sense of scale. 

Millions, Billions & Trillions..., David Adler and Edward Miller
