Reader comments
This book is so practical for third graders! When I deliver express delivery, I often have to calculate the distance and time between different addresses, so I understand the importance of computing power. There are many calculation problems in this book, and the difficulty gradually increases, just like my delivery journey, from easy to difficult. It can also help children master calculation methods systematically, which is really good. Just like the book says "Practice makes perfect", practice more and you will be able to calculate the answer quickly and accurately!
