CROSS-SENSE AS A TECHNIQUE FOR DEVELOPING CRITICAL THINKING IN PRIMARY SCHOOL MATHEMATICS LESSONS

Abstract

Abstract. The article is dedicated to exploring cross-sense as an innovative technique within the technology of developing critical thinking in primary school mathematics lessons. The study analyzes the theoretical foundations of critical thinking, considered a key competency that enables students to analyze information, establish cause-and-effect relationships, and make informed decisions. Particular attention is given to cross-sense as a next-generation puzzle that combines the best qualities of several intellectual activities: riddles, rebuses, and puzzles, fostering the development of analytical skills and systemic thinking. The article describes the methodological aspects of integrating cross-sense into the educational process, including stages of student preparation, organization of group interactions, and reflection on outcomes. The main advantages of this technique are identified, such as increased student motivation, stimulation of cognitive activity, and the development of self-regulation and collaboration skills. At the same time, limitations are noted, particularly the need to adapt tasks to students’ mathematical proficiency levels and the additional effort required from teachers to prepare materials. Based on the analysis, practical recommendations for educators are proposed, including the use of simple examples at the initial stage, gradual escalation of task complexity, and combining cross-sense with other teaching methods to ensure variety. The study emphasizes the alignment of crossense with constructivist principles, which highlight the active role of students in knowledge construction, as well as its suitability for the developmental characteristics of primary school students, making this technique particularly effective in early education. Future research directions are outlined, including the adaptation of crossense to other academic disciplines and the development of digital versions for use on interactive platforms. The importance of integrating innovative methods into the educational process to cultivate critical thinking as a cornerstone of modern education is underscored.
