口算是数学中最为基础的知识技能,也是学生思维能力的重要体现,但却容易被教师忽略。新课改将口算教学提高到了新的位置,加强对口算能力培养是小学数学教学的重要任务,笔者联系小学数学口算教学实际,就如何抓住“口算”这一个小题进行了研究。一、概述口算又叫做心算,是指学生在不借助任何工具情况下,通过看、思结合结算出正确结构的计算方式。“小题大做”是指将小事作为大事来做,有不值得做的意思。在小学数学教学中,口算知识难度 Mouth arithmetic is the most basic knowledge and skills in mathematics, but also an important manifestation of the thinking ability of students, but it is easy to be ignored by teachers. The new curriculum reform will increase the teaching of oral arithmetic to a new position. To strengthen the training of oral arithmetic is an important task in elementary mathematics teaching. The author studies the problem of how to grasp the teaching of mathematics in primary schools. First, an overview Miao-cheng, also known as mental arithmetic, refers to the students without resorting to any tools, through the look, think combined with the calculation of the correct structure of the calculation. “Make a fuss” refers to the trivial matter as a major event to do, it is not worth the meaning of doing. In primary school mathematics teaching, the difficulty of calculating knowledge
