The new curriculum reform pays attention to the occurrence and development of knowledge, trains students to observe the society and think about problems from the viewpoint of mathematics, strengthens the consciousness of applied mathematics, and attaches importance to the combination of practice and applied mathematics consciousness. Teachers should strengthen mathematics application teaching, let students learn independently, attach importance to extracurricular practice, promote students to gradually form and develop mathematics application consciousness and improve their practical application ability.

Keywords: mathematics application, life experience, applying what you have learned.

The new curriculum reform pays attention to the occurrence and development of knowledge, trains students to observe the society and think about problems from a mathematical point of view, enhances the consciousness of applying mathematics, and truly enables students to apply what they have learned. In recent years, I adhere to the new curriculum standards as the guiding ideology, attach importance to practice, strengthen the cultivation of students' mathematical application ability, and do some exploration. Here I want to talk about some thoughts on this issue.

First, the theoretical basis

1. The development of mathematics is the history of its application.

Judging from the early development of mathematics, mathematics originated from the needs of human real life. In the simple commodity exchange and redistribution, human beings have produced the concept of number. There are many geometric problems in the earliest mathematical works "Rhine papyrus" and "Moscow papyrus" handed down from ancient Egypt, most of which are related to the calculation of land area and grain pile volume; China's earliest extant mathematical work "Zhou Bi suan Jing", the main achievement is Pythagorean theorem and its application in astronomical measurement.

In modern times, especially in modern times, on the one hand, the core research of mathematics has become more and more abstract; On the other hand, the application of mathematics is becoming more and more extensive. Mathematics is not only widely used in physics, chemistry, biology and other natural sciences, but also widely used in economics and sociology. In the increasingly developing information society, even ordinary workers must have basic mathematical operation ability, and the ability to observe and analyze their work, life and even engage in economic and political activities by using mathematical ideas-deposit, interest, stock, investment, insurance, cost, profit, discount, installment payment, etc. It can be said that mathematics is one of the most basic and important tools for human activities.
