数学是人们对客观世界定性把握和定量刻画、逐渐抽象概括、形成方法和理论,并进行广泛应用的过程。从教近20年,发现一个普遍现象,从学生的作业以及测试情况来看,不但低年级学生的计算总是出错较多,高年级也有相同的现象,分析原因,正是从低年级开始没有对计算功底打下良好的基础。计算能力是一项基本的数学能力,培养小学生一定的计算能力,是小学数学教学的一项重要任务。一、手指操对小学生思维发展及计算能力的提高
Mathematics is a process by which people qualitatively grasp and quantitatively describe the objective world, abstract them gradually, form methods and theories, and make them widely used. From the teaching of nearly 20 years, found a common phenomenon, from the students’ homework and test situation, not only the calculation of lower grades students always wrong, higher grades have the same phenomenon, analyze the reason, it is from the beginning of junior grade no right Calculating skills lay a good foundation. Computational ability is a basic mathematical ability, to develop a certain computing power of primary school students, is an important task in primary school mathematics teaching. First, finger exercises on the thinking of primary school students to develop and improve computing power
