摘  要：很多数学知识本身比较抽象，且蕴含的信息量很大，如果在教学中依靠单纯讲授或者针对分析予以呈现，势必难以帮助学生精准把握其内涵与实质，预期教学效果自然也不够理想。而依托动手操作进行小学数学概念、公式、定律教学，则可以使抽象的教学内容直观化、具体性、形象性地呈现，既激发了学生的兴趣，加深了学生的理解，又可以使学习内容中隐含的诸多潜在因素得以深度挖掘，使学生对数学的把握更为充分、到位、深入。尤其在小学数学几何部分知识教学时，教师更需要加强对动手操作条件的创设、机会的创造、工具的提供，以帮助学生在实践、操作、应用中理解数学内涵，获得认知迁移。

Effective Strategies for Cultivating Students' Practical Ability in Primary School Mathematics Teaching

ZENG Meie  （Xiaoxi Central Primary School，Pinghe County，Fujian Province，China）

【Abstract】A lot of mathematics knowledge itself is relatively abstract and contains a large amount of information. If you rely on simple teaching or present analysis in the teaching，it will inevitably be difficult to help students accurately grasp its connotation and essence，and the expected teaching effect is naturally not ideal. Relying on hands-on operation to teach primary school mathematics concepts，formulas，and laws can make the abstract teaching content intuitive，concrete and vivid，which not only stimulates students interest，deepens their understanding，but also make in-depth exploration of many potential factors hidden in the learning content，so that students can grasp mathematics more fully，in place and in-depth. Especially in the teaching of primary school mathematics and geometry knowledge，teachers need to strengthen the creation of hands-on operating conditions，the creation of opportunities，and the provision of tools to help students understand the connotation of mathematics in practice，operation，and application，and obtain cognitive transfer.

数学一门以抽象、逻辑、空间思维为载体的认知工具，其呈现形式多种多样，且内涵比較丰富、外延比较宽泛。很多数学知识，在本质上都是对应数量关系和空间形式在人脑中以客观的形式进行反映。而学生对数学学习内容的理解与掌握深度、广度、效度，则直接影响着其数学认识发展，这使得做好数学教学的重要性不言而喻。很多教师在进行小学数学教学时，采用图画式、定义式、描述式等方式开展指导，由于教学方法的选择基本停留在表面，以致学生对数学概念的把握也比较浅显，难以真正领悟其内涵与实质，也难以培养动手操作能力。……
