The common mathematical models in middle schools are: equation model, inequality model, function model, geometric model and statistical model. We also refer to using mathematical model as an application modeling method to solve practical problems. There are five models to write.

. It is best to write your own paper. If you are taking part in a competition, you will find it on the Internet and it will be searched out.

This is the requirement of a mathematical contest modeling test paper. Please refer to (1) to model the standard components of paper.

As a meaningful attempt of inquiry learning, model essay can cultivate students' ability to find and solve problems. Generally speaking, the standard components of modeling papers are composed of title, abstract, body, conclusion, references and so on. Now, let's make a brief description of each part.

1. Title

The title is the first impression to the judges, so the title of the paper must avoid the phenomenon of unclear reference and expression. It is suggested to write out the model involved in the paper or the calculation method used in the topic, such as "calculating the income of discounts and coupons in shopping malls by probability method"

2. Summary

Abstract is an important part of the paper. Concise language should be used to describe the core ideas and main viewpoints of the paper. If you have some innovations, you must explain them abstractly. Further, you must put some numerical results in the abstract, such as: "Our final calculation shows that the discount rate is 23% higher than the rebate rate of consumers." The summary should be written at the end. You shouldn't write an abstract until the rest of the paper is finished. Because the abstract is the concentrated expression of the theme and core content of the paper, you can only write the abstract if you finish all the papers and make the style series of the papers clear.

Generally, it is divided into three parts, and the center of the whole paper is expressed in three sentences.

In the first sentence, what model to use and what problems to solve.

The second sentence is how to solve the problem.

The third sentence, what is the final result?

Of course, for junior students, you don't have to write an abstract.

3. Text

The text is the core and the most important part of the paper. In the writing of the thesis, it should be carried out step by step in the way of "asking questions-analyzing problems-selecting models-establishing models-drawing conclusions". Among them, raising and analyzing problems should be clear and to the point, while selecting and establishing models should have clear objectives, detailed data, reasonable formulas and accurate calculations. In writing articles, we should try not to use simplicity.

4. Conclusion

The conclusion of this paper reflects the research results of this paper. It can be said that only when the conclusion of this paper can stand scrutiny can the paper get a higher evaluation. The writing of conclusion should pay attention to the accuracy of words and keep absolute unity with the phenomena or data described or demonstrated in this paper. It is also necessary to make self-comments on the conclusion, and it is best to extend the conclusion to social practice for testing.

5. Reference materials

If other people's materials are used in the paper, the author and application source of the cited article must be indicated at the end of the paper.

(B), modeling paper writing steps

1. Determine the theme

Choose a problem in your life that interests you as the research object, and set the topic of the paper according to the research object. It is best to find one or more teachers to help arrange research topics. After determining the topic, you should write a writing plan for the instructor and ask for their suggestions on the plan.

2. Carry out scientific research projects

Go to the library and the Internet to find information related to the project, observe related events and collect information related to the project. At the same time, if possible, you can visit experts and scholars in related fields. Then use the relevant knowledge you have learned to organize the information collected in the early stage to demonstrate the structure of the paper. After completing these tasks, you should make a project schedule. This can ensure the gradual writing of the paper. Remember to communicate with teachers and parents constantly after writing the paper, so that teachers and parents can correct the obvious mistakes in the paper and put forward some better research suggestions. After writing the paper, you must draw a conclusion. Remember, it doesn't matter that the possible results are inconsistent with the assumptions after the results of the paper come out. Don't force the result to meet the hypothesis. As long as you strictly follow the scientific method in the discussion, your paper is still quite valuable. Finally, you need to write a summary. The number of words in the abstract should be about one tenth of the number of words in the paper.

3. Finish the thesis writing

After completing the above steps, the complete paper can be freshly baked. After you finish your paper, you must read it again to check whether there are any typos, calculation errors, graphic shifts or deviations. Finally, you should write a thank-you letter at the end of the paper, thanking everyone who helped you finish this paper.
