What does a million look like? A billion? A trillion? These huge numbers are hard to visualize. This book explains quantities in terms children can understand. For example, one million dollars could buy two full pizzas a day for more than sixty-eight years, and it would take the heads of ten thousand people together to have one billion hairs. The dynamic math duo of David A. Adler and Edward Miller explain the concepts of millions, billions, and trillions in a light hearted way.
