CONCEPT OF UNDERSTANDING IN EDUCATION FOR FIRST CLASSES OF EDUCATIONAL EDUCATION

Summary/Abstract: The notion of an unknown number plays an important role in switching from arithmetic to an algebra, but it also represents a source of confusion that arises in algebra teaching. In previous research, the dominant view is that the unknown should be introduced in the teaching of arithmetic, gradually, while students acquire the skills in the account. In constructing the meaning of new concepts, a great deal of different representations were used. In this paper we are dealing with the analysis of the introduction of the term unknown in the textbooks for the first grade of elementary education from the aspect of marking the unknown, the way of reaching its value and the use of different representations. The research showed that there is no single position in the textbooks about marking the unknown and about how to find its value. Also, in some textbooks, insufficient attention is paid to the ways of representing this term.
