数学学习的中心内容是计算,只有迅速、准确地进行各类计算,才是数学学习有效的根本保障。而口算能力又是计算的基础,对学生基本的运算能力有着极其重要的影响。口算能力的训练,有助于培养学生敏锐的观察力,有助于培养学生综合的思维能力,有助于培养学生的快速反应能力,有助于学生创新意识的培养。口算能力在小学生数学学习过程中有着重要的作用,数与代数阶段的整数的加减乘除、小数计算、分数计算,空间与图形的面积体积的计算,统计概率中数据的分析与计算,综合与实践
The center of mathematics learning is computing, and only calculating all kinds of calculations quickly and accurately is the fundamental guarantee for the effective learning of mathematics. However, the ability to calculate accounts is the basis of calculation, which has an extremely important influence on students’ basic computing ability. Mouth arithmetic ability training, help to develop students keen observation, help to develop students’ comprehensive thinking ability, help to develop students’ rapid response ability, help to cultivate students’ innovative consciousness. The ability of arithmetic in primary school mathematics learning process has an important role in the number of algebraic stages of the addition, subtraction, multiplication and division, fractional calculation, space and graphics area volume calculation, statistical probability of the data in the analysis and calculation, synthesis and practice
