Once again the author of the popular MathStart series explains a math concept in a simple, exuberant story with bright, clear pictures.

内容简介

It's hard work, taking care of 5 little ducks. But when each little duck comes home with a friend -- oh, no! Now it's double the ducks and double the work. How can 1 little boy get everything done?

Understanding how to double numbers helps children master both addition and multiplication. Fun, friendship, and lots of ducks make learning this essential skill both easy and entertaining.
