口算是学生学习数学的基础,低年级口算教学能否达到大纲规定的要求,将直接关系到中高年级的数学计算能力的形成。欠发达地区的农村小学在没有多媒体等先进的电化教学器材的情况下,如何利用自制教具和灵活多样的教学方法来培养低年级学生的口算能力?教学中我从以下几个方面进行了探索。一、手脑并用直观演示建立表象从直接感知实物过渡到表象的运算,是低年级口算的重 Mouth count is the basis for students to learn mathematics, low grade oral education can meet the outline requirements, will be directly related to the formation of high school mathematics computing power. In the less developed areas of rural primary schools in the absence of multimedia and other advanced teaching materials, how to use self-made teaching aids and flexible teaching methods to cultivate the ability of lower-level students in my teaching? I am teaching from the following aspects to explore. First, the brain and intuitive presentation to establish the image from the direct perception of the physical transition to the operation of the image, is the low grade port count
