Since the first grade of primary school, I have been using "Diandian" and "Diandian" published by Rong. In fact, these two books have their own uses and advantages.

Hour-by-hour is a comprehensive application innovation workbook synchronized with the teaching materials, including basic exercises and promotion exercises. It is a good exercise book that is used synchronously with the textbook. The topic is novel and there are some learning methods.

Hugging is a textbook that is synchronized with the explanation in class. With the use of in-class explanations, it can be previewed before class and consolidated after class. Generally speaking, it is a textbook interpretation and a teaching aid. Chinese allows you to read through the text and understand new words; Mathematics can make you know more about what you have learned and improve your knowledge reserve. English can be familiar with grammar and learn texts and words. Anyway, no matter chemical geography or anything else, you can use two books, Diandian and Diandian. I suggest that Diandian and Diandian can be used together. One can be familiar with textbooks, and the other can be consolidated and improved. Dot also has exercises, but if you want to do exercises specially, it is more appropriate to use dot.

Hope to adopt yo ~
