Teaching Fraction Calculations for Grade 4 Students In Vietnam Oriented Toward the Development of Mathematical Thinking and Reasoning Competency

In the context of Vietnam’s vigorous general education reform, the current curriculum defines Mathematical Thinking and Reasoning Competency as one of the five components of mathematical competence that students need to achieve. This paper clarifies the manifestations of mathematical thinking and reasoning ability, and proposes a process for teaching fraction calculations to 4th-grade students in a way that fosters this competency. Illustrative examples demonstrate the feasibility and effectiveness of this approach, contributing to the enhancement of math teaching quality and aligning with the current educational reform direction.
