	<span style=\"line-height:1.5;\">小学生数感的培养在数学教育中日益重视，而数感发展的关键期在低学段。一年级小学科学教材(教科版)“比较与测量”单元是跨学科数感培养的一个良好载体，本文分析和提取该单元中能够进行数感培养的素材，在原有科学教学环节上设计渗透数感培养的教学方案，并以此开展相关教学实践：1) “在观察中比较”，通过实践操作来开展数感培养；2) “用手来测量”，重视估算在数感培养中的必要性。在此基础上，提出培养策略：1) 善于挖掘素材，打造良好载体；2) 弥补薄弱环节，加强估算地位；3) 提高自身素养，转变教育观念。<br />
The cultivation of elementary school students’ sense of number is increasingly valued in mathe-matics education, and the critical period for the development of number sense is in the lower grades. The “Comparison and Measurement” unit of the first grade primary school science textbook (Educational Science Publishing House) is a good carrier for interdisciplinary number sense cultivation. This article analyzes and extracts the materials that can be used for number sense cul-tivation in this unit, and designs the teaching scheme that penetrates the training of number sense in the original science teaching links, and carries out relevant teaching practice: 1) “Compare in observation”, carry out the number sense cultivation through practical operation; 2) “Measure by hand”, and pay attention to the necessity of estimating in the number sense cultivation. On this basis, this paper puts forward training strategies: 1) Be good at digging materials and create good carriers; 2) Make up for weak links and strengthen the estimation status; 3) Improve self-literacy and change education concepts.</span><span style=\"line-height:1.5;\"></span>
