In the article the topicality of the problem of studentss’ algorithmic culture forming is revealed.It is substantiated by the fact that in school mathematics algorithmic line begins to develop in primary school. Students of junior grades study the simplest algorithms of arithmetic operations, the sequence of arithmetic operations with natural numbers when solving problems and exercises, which is a form of algorithmic propaedeutic culture. The didactic conditions of formation of algorithmic culture of students in the study of school mathematics are defined, as well as the general scheme of the formation of the algorithmic culture of students in the study of school mathematics, which includes the following stages: the disclosure of the content and method of algorithmization; familiarity with the concept of the algorithm and its properties; formation of abilities to use basic algorithms for computing; formation of basic skills and logging algorithms in different forms; formation of abilities to use basic algorithmic structures. An analysis of the content of school mathematics of the 5–6 grades allowed to select the rule, which can be algorithmic: comparison of natural numbers and fractions; actions with fractions; rounding integers and fractions; finding the arithmetic mean; calculation of interest; finding the greatest common divisor; finding the least common multiple and others. We consider four types of means of signs and symbolic visibility, which are used in the assimilation of mathematical concepts and systematization of mathematical knowledge. Methodological recommendations for the assimilation of such rules with the help of block diagrams and tables are given. The examples of tables in which the rules can be learned from the actions of decimals and the rule for finding the greatest common divisor of two integers, as well as a diagram comparing two integers are given. The proposed tables and diagrams can be used in the process of studying the relevant school mathematics by the students of the 5–6 grades.
