口算是笔算的基础,口算的热练程度制约着笔算能力的高低。这是小学数学教学的一条规律。不但低年级要加强口算训练,中、高年级也要加强口算能力的培养。下面仅就口算练习内容的安排、形式、方法等问题,谈点做法。 一、合理安排口算练习的内容。要使口算教学达到预期的效果,必须在备课时 Mouth count is the basis for calculating, accounting for the degree of thermal training limit the level of abilities. This is a law of primary school mathematics teaching. Not only the lower grades should strengthen their oral training, middle and senior grades should also strengthen their ability to train their words and minds. The following only on the mouth of exercise content arrangements, forms, methods and other issues, talk about practices. First, reasonable arrangements for oral exercise content. To make the mouth count teaching achieve the desired effect, must prepare lesson time
