The International Mathematics Olympiad “Kangaroo” has become one of the world’s largest mathematics competitions for schoolchildren, fostering interest in problem-solving and logical reasoning from an early age. Effective preparation of primary school students for this contest requires a methodology that balances the development of conceptual understanding, procedural fluency, and motivational factors. This article elucidates an evidence-based instructional model designed to equip pupils of grades 1–4 with the skills and dispositions needed for successful participation. Drawing on sociocultural learning theory, metacognitive strategy research, and recent findings in mathematics education, the study combines classroom observations, quasi-experimental interventions, and qualitative feedback from teachers and students across four Uzbek primary schools. Results demonstrate significant improvements in students’ problem-solving accuracy, flexible thinking, and mathematical self-efficacy when the proposed methodology is implemented over a 12-week period. The discussion highlights pedagogical implications for curriculum designers, teacher trainers, and policymakers aiming to integrate Olympiad-oriented activities into everyday mathematics instruction without compromising national standards.
