新教材背景下低段数学综合实践教学探究——以《装饰图中的奥秘》为例

Research on Integrated Practical Mathematics Teaching in the Lower Grades under the New Curriculum Context—A Case Study of The Mystery of Decorative Patterns

摘要: “综合与实践”板块是小学课程的重要组成部分。与“数与代数”“图形与几何”等板块内容不同，更加致力于提高学生解决实际问题的能力，形成和发展模型意识、创新意识。本文结合北师大小学数学新教材变化，以《装饰图中的奥秘》为例，从课标承载、教学支撑、实践落地三方面展开探索，从目标定位、内容构建、过程规范、评价优化四方面提出实践路径，强调紧扣教学核心、生活化分层设计、规范课堂流程、多元激励评价。从而提升学生解决实际生活问题的能力，发展数学核心素养、综合素养。

Abstract: The “Comprehensive Practice” strand constitutes a pivotal component of the primary mathematics curriculum. Distinguished from domains such as “Number and Algebra” or “Graphics and Geometry”, this strand is specifically dedicated to enhancing students’ capacity to solve real-world problems while fostering model awareness and innovation. Grounded in the revisions of the Beijing Normal University (BNU) primary mathematics textbook series, this paper takes The Mystery of Decorative Patterns as a case study. It explores three dimensions—curriculum alignment, pedagogical support, and practical implementation, and proposes a fourfold pathway involving goal orientation, content structuring, procedural standardization, and evaluative optimization. By emphasizing core instructional focus, tiered life-relevant design, standardized classroom protocols, and diversified incentive evaluations, the study aims to elevate students’ problem-solving competencies and advance their core mathematical and comprehensive literacies.
