This is a new self-defined operation, the main purpose of which is to examine students' adaptability and understanding of new things, which is conducive to the cultivation of students' autonomous learning ability. In today's math test, we should pay attention to novelty. Of course, we must do the old questions, but if some new mathematical questions and ideas can replace the old questions and have the flavor of the times, then such questions are the objects we pursue. In primary school mathematics teaching, we often find that the teaching content is boring and can't well tap students' innovative ability and interest in mathematics. Therefore, a new round of curriculum reform is being implemented nationwide. The purpose of curriculum reform is to put people first and give full play to the role of students in the classroom. At the same time, it also brings new ideas to our proposition teacher.

However, one thing is that this type of topic does not account for a large proportion in a test paper, so proper practice is enough at ordinary times. The focus is on the practice of basic topics, and we must not put the cart before the horse, and so is the proposition. Often such questions are not difficult, and students with strong adaptability can easily answer them without doing such questions. For a test paper with a score of 100, the number of innovative questions will not exceed 5, and the number of questions should be controlled as much as possible at 20.
