Abstract
This thesis explores the role of contextual tasks in the formation of mathematical literacy of students in math lessons at school. Mathematical literacy includes not only the ability to solve mathematical problems, but also an understanding of mathematical concepts and their application in real situations. Contextual problems are mathematical problems that are placed in a realistic context, which allows students to see the connection between mathematics and everyday life. The article discusses the advantages of using contextual tasks, methods of their construction, as well as the impact of contextual tasks on the development of mathematical literacy of students.
