摘 要：数感作为数学核心素养的重要组成部分，对学生的数学学习和未来发展具有深远影响。本研究基于当前小学数学教学中数感培养存在的问题，如教学方式单一、情境创设不足及评价体系不够完善等背景，旨在探索有效的数感培养策略。研究采用问卷调查、课堂观察与案例分析相结合的方法，选取某地区多所小学的数学课堂为研究对象，深入分析学生数感发展的现状及其影响因素。研究发现，通过创设贴近生活的教学情境、强化估算与数量关系的理解、运用多样化的教学工具以及构建多元评价机制，能够显著提升学生的数感水平。本研究的创新点在于提出了一套系统化、可操作性强的数感培养框架，并强调了教师在教学设计中的关键作用。研究成果为小学数学教学提供了理论支持与实践指导，有助于推动学生数学核心素养的整体发展。

摘 要：As an important part of the core literacy of mathematics, number sense has a profound impact on students' mathematics learning and future development. This study is based on the problems existing in the cultivation of number sense in the current primary school mathematics teaching, such as single teaching methods, insufficient situation creation and imperfect evaluation system, and aims to explore effective cultivation strategies for number sense. The research adopts the method of combining questionnaire survey, classroom observation and case analysis, and selects mathematics classes in many primary schools in a certain area as the research ob ject to deeply analyze the current situation of students' number sense development and its influencing factors. It is found that students' sense of number can be significantly improved by creating the teaching situation of life, strengthening the understanding of teaching and quantity relationship, the use of diversified teaching tools and the construction of multiple evaluation mechanism. The innovation of this study is to propose a systematic and operable fr amework for number sense cultivation, and to emphasize the key role of teachers in teaching design. The research results provide theoretical support and practical guidance for primary school mathematics teaching, and help to promote the overall development of students' core literacy of mathematics.
