Through solving the problems that are embedded in a story a student will learn how to distinguish the important information from unimportant one. Although the questions require only multiplication, division, subtraction, addition every problem is different and needs a new approach.

At the end of the book, there is a section containing hints, which guide the reader to the correct way of looking at a problem. It is likely that a child will be able to find the solution after reading a hint. Using this approach to solving word problems will make children feel proud and confident, as well as ignite a desire in them to try more problems. This book is translated and published in China in 2014.
