Abstract
The article raises the problem of replacing the majority of students' idea of chemistry as a difficult subject with the idea of chemistry as an easy and interesting subject. Today, most schoolchildren do not have the opportunity to establish a deep connection between chemistry and mathematics, demonstrate the inability to apply the knowledge gained in one subject, the underdevelopment of the application of concepts in accordance with the subject in practice, which implies serious issues of international tests PISA, TIMSS, etc. As a solution to this problem, the authors propose ways to improve the quality of knowledge in chemistry through the development of interdisciplinary connections of chemistry and mathematics. The chemistry teacher is called upon to reveal the hidden enthusiasm (energy) of the child, to give motivation to remember and automatically apply the knowledge gained in mathematics lessons about the types of numbers, ways of handling numbers, formulas, the ability to transform them, the designation of physical quantities, units of measurement, etc. After each lesson, the student can include in the report on the passed topic, independently look for ways, life hacks for an easy and quick solution of the problem. It is necessary to combine theoretical knowledge, problem solving and parallel possession of experience. It is important for students to combine viewing the experience from a virtual laboratory, discussion, analysis, and preparation of a report, albeit a simple one. As a result, the authors note, thanks to the optimization of teaching subjects in interdisciplinary communication, many students in the classroom have developed the skills of easy and quick solution of problems of chemical content, increased interest in subjects.
