What does it mean to revise the textbook of mathematics for the first grade?
It means to revise the revised textbook.

When a book is published, there will be some mistakes more or less, such as some typos or word order disorder, and so will textbooks. Therefore, before the mass production of teaching materials, special personnel will be assigned to check and modify them, or errors will be found in the use process and will be revised in the next printing and publication. The so-called "modification" means modification.

Basic basis of textbook revision:

1, the textbook needs to be revised according to the requirements of curriculum standards. Compared with the experimental draft, the formal version of the curriculum standard has not changed much in basic concepts, design ideas, content framework and so on. The experimental teaching material is compiled according to the experimental draft of curriculum standard, which fully embodies the requirements of the experimental draft of curriculum standard.

2. In the case that the curriculum standards have not changed fundamentally, the revision of the teaching materials has not changed much in the overall writing ideas and content arrangement system of the teaching materials. The revised textbook maintains and develops the following characteristics of the original experimental textbook; A knowledge system that highlights man and the biosphere is constructed.

3. Strengthen the education of emotion, attitude and values through various channels; Through serialized and diversified scientific inquiry activities, promote the change of learning methods, implement scientific method education and improve students' scientific inquiry ability; Pay attention to reflect the new progress of biotechnology. Compared with the experimental draft of the curriculum standard, the formal version of the curriculum standard emphasizes the teaching of core concepts and strengthens the content requirements of animal groups.

In view of these changes in curriculum standards, it is an important task to highlight the teaching of important biological concepts when revising textbooks. Compared with the experimental textbook, the revised textbook pays more attention to the study of important biological concepts.

5. "Summary of this chapter" at the end of each chapter guides students to sort out and summarize the important concepts learned in this chapter. Because the content requirements of animal groups have been increased in the official curriculum standard, the revised textbook for the first volume of Grade 8 will greatly adjust and supplement the existing contents of coelenterates, flatworms and other animal groups to meet the requirements of the curriculum standard.
