Keywords: plane figures, productive strategies, specific mathematical competences


INТRODUCTION: The development of specific mathematical competences from the competency cluster “Plane figures” is one of the important factors for achieving effective education in mathematics in primary school.

PURPOSE OF STUDY: The purpose of this article is the presentation of the competences concept and especially the concept of the objective specific mathematical competences as well as the options for their development in and through education in mathematics in Grades 1-4.  

METHODS: During the experimental work the researchers performed qualitative and quantitative study of the topics presented above. The following methods were applied: a didactical experiment, observation, test, content analysis, and a mathematical-statistical method for data processing.

RESULTS: As a result of the experimental work it was determined that the percentage of fourth graders who failed to solve a geometry text task decreased from 49.61% to 9.32%. The percentage of those students who failed to draw a circle with a given radius and an angle according to a given grade decreased from 38.95% to 8.17%. Additionally, the percentage of the students who correctly solved a geometry text tasks increased from 15.2% to 23.1%. The difference in the results is proven to be of statistical significance.  

CONCLUSIONS: Owing to the applied methodology system of work where productive strategies, methods and approaches were used, the specific mathematical competences from the competency cluster “Plane figures” were developed in their completeness in primary school students.
