Abstract
Today, the problem of developing the functional literacy of schoolchildren is relevant at the community level. In this regard, new requirements are imposed on the level of professional training of future mathematics teachers. The authors consider the issue of preparing future mathematics teachers to develop students' mathematical literacy. The works of scientists on the development of functional literacy of schoolchildren were studied and the concepts of "model", "mathematical modeling" were explained. In addition, the specifics of the method of mathematical modeling in the process of teaching mathematics in secondary school have been clarified, and the pedagogical conditions for using the modeling method have been determined. It is shown that mathematical modeling is not only a tool for solving applied problems, but also a way of developing intellectual skills that a student must master.
