Methods for solving textual and non-standard tasks

One of the most important tasks of primary education is the development of logical thinking. Textual and non-standard tasks have a special place in the formation of students' thinking abilities. By mastering the solution of such problems, we form in the student such qualities as search for innovation, self-attitude, perseverance. The article discusses textual and non-standard tasks and solutions found in the course of elementary mathematics, the technology of criterion-based assessment. The concepts of "text task", "non-standard task" were defined. This article presents a methodology for criterion-based assessment of students' academic achievements in mathematics lessons. The peculiarity of this technology is that when solving a task, students create descriptors, which are subsequently used in formative and aggregate assessments. Each descriptor is a step in the algorithm that solves the problem. Particular attention is paid to the use of various methods by primary school teachers in solving text problems, the importance of observing and supporting the child's non-standard ideas. The habit of finding other ways to solve the problem, the ability to use various ways and means of solving the problem plays a huge role in the future work, scientific and creative activity of the student. As a result of the research work, the main recommendations for finding a solution to text and non-standard tasks were developed. The advantages of using the criterion-based assessment system in mathematics lessons are revealed.
