经过摸索与实践,我认为提高学生的计算能力,可以从以下几个方面入手:一、狠抓口算训练,打好计算基础任何一道整数、分数或小数的四则运算,最终都要分解成一些基本口算题加以解决。笔算根据算理分析可以落实到口算。如,在教学北师大版三年级下册《电影院》时,让学生分析题目列出算式26×21后,在教学两位数乘两位数的进位乘法笔算前,可以把这道题分解为如下两种方法利用之前学的知识而得出结果:126×20=520 26×1=26 520+26=546220×21=420 6×21=126 420+126=546 After groping and practice, I think to improve students’ computing ability, we can start from the following aspects: First, pay close attention to training, lay a good foundation for calculating any integer, fractional or decimal arithmetic, and ultimately must be broken down into some basic Mouth problem to be solved. Pen calculation according to the analysis of the logic can be implemented to the mouth count. For example, in the teaching of the third edition of the Beijing Normal University, “Cinema”, let students analyze the problem listed in the formula 26 × 21, the teaching of double-digit by two-digit carry multiplication pen calculation before, you can put this problem decomposition Results are derived from prior knowledge using the following two methods: 126 × 20 = 520 26 × 1 = 26 520 + 26 = 546220 × 21 = 420 6 × 21 = 126 420 + 126 = 546
