The purpose of the research is the determination of the role of tasks of integrative content in the implementation of the continuity principle in teaching mathematics. During the research, we used the following methods: analysis of school mathematics curricula and educational programs for training future mathematics teachers, search, and analysis of relevant problems with further formation of problems with integrative content based on them; generalization of own and advanced pedagogical experience regarding the application of computer mathematics systems in the educational process of secondary and higher schools. As a result of the research, the following conclusions were made: the use of problems of integrative content provides an opportunity to form integrated images of mathematical material, as well as to consolidate mathematical objects, the use (by subjects of training) of scientific methods of cognition – observation, analogy, analysis, synthesis, comparison. This approach was implemented from the point of view of the integration of teaching methods, such as the method of addition, the technology of enlargement of didactic units, and the method of contrast. And also, from the point of view of teaching aids, the use of graphic illustrations, information and communication technologies, schemes, and algorithms of analytical statements. This practice ensures the formation of generalized mathematical skills and, as a result, the formation of integrative mathematical abilities and beliefs based on them, which will enable the implementation of the continuity principle in the study of mathematics between different branches of education. It is possible only with an in-depth study of specific mathematical problems and under the condition of using a heuristic approach to learning with the using ICT tools.
