There are several reasons for the problems in the first volume of mathematics published by Beijing Normal University. The first problem is that the knowledge arrangement of the first volume of mathematics textbooks published by Beijing Normal University may be somewhat unreasonable in structure, that is to say, when learning knowledge, some knowledge does not have a gradual process, and then students' acceptance is not very good.

Then the second problem is that there are some minor mistakes in some chapters of the book. Although these small mistakes will not have a great impact, they are still an aspect that needs to be revised.

Then the third problem is that more humanized illustrations can be added to the textbook published by Beijing Normal University, which means that children can be taught more about this. Therefore, the above is the main problem of the first volume of mathematics in grade one of Beijing Normal University.
