Today, we are talking about the problems faced by elementary school students in mastering mathematics and their search for solutions. Undoubtedly, there is a need to systematize the accumulated experience on scientific reasoning in terms of how to transfer educational information and a technological approach to its study . The ability to organize symbolic activities within the framework of mastering is very important for the teacher, because he can present a large amount of information in a visible, "compressed" format at the same time.
