为了探索教学规律,改进教学方法,提高小学生的计算能力,我们协助护国镇小学在二年级四班、五班进行了口算教学的实验。下面是我们的实验情况汇报。把握“两头”明确方向首先认真学习大纲、教材。明确小学数学四册教材中“一位数乘、除两位数”口算教学内容的地位和作用:1.它是多位数除法试商的关键,是笔算多位数除法必备的基础。2.它是加快笔算乘法、
In order to explore the law of teaching, improve teaching methods and improve the computing power of pupils, we assisted Huoguozhen Primary School in the fourth grade and the fifth grade in Grade Two to conduct oral arithmetic experiments. The following is our experimental report. Grasp the “two” clear direction First serious study outline, teaching material. Clear four textbooks of primary mathematics, “one-by-multiple, in addition to two-digit” oral education content status and role: 1. It is the key to the multi-digit division test, is the necessary basis for calculating multi-digit division. 2. It is to speed up the calculation of multiplication,
