小学数学运算主要是整数、小数和分数的加减乘除四则运算,当然也包括一些变形,如分数的约分和通分等,但约分和通分实质是乘除运算,因此,小学数学运算主要是数的四则计算,计算教学是小学数学的主要内容,培养计算能力也是小学数学教学的主要日标,下面就计算教学谈一些自己的看法。一、教学中存在的问题1.教师方面的问题。(1)重技能轻原理。计算教学包括概念的建立、法则的探究、法则的运用以及技能的训练,例如分数的加法,首先要建立分数和的概念,第二要引导学生
Primary mathematics is mainly integer, fractional and fractional addition, subtraction, multiplication and division of four operations, of course, including some deformation, such as the fraction of points and pass points, but about points and pass points is essentially the multiplication and division operations, so the primary mathematical operation Is the calculation of the number of four, the calculation of teaching is the primary content of primary school mathematics, training is also the primary computing capacity of primary mathematics teaching standards, the following discussion on computing teaching to talk about some of their own views. First, the problems in teaching 1. Teachers’ problems. (1) heavy skills light principle. Computational teaching includes the establishment of concepts, the exploration of laws, the application of rules and the training of skills, such as the addition of scores. The first is to establish the concept of fractional sum. The second is to guide students
