数学是一门工具课,在生产与科学技术中,用数学去解决实际问题,除了牢固掌握数学基础知识以外,更重要的需要具有正确,迅速的计算能力。小学数学教学大纲中指出:“小学数学教学的一项重要任务是培养学生的计算能力。”但从当前小学的实际情况来看,学生们的计算能力还是很差,具体表现在不少学生对数学上的法则、性质、定律的运用不够灵活、计算过程繁琐、速度缓慢、正确率也不够高。怎样改变这一现状,
Mathematics is a tool lesson in which mathematics is used to solve practical problems in production and science and technology. In addition to firmly grasping the basics of mathematics, it is more important to have the correct and rapid computing power. Primary school mathematics syllabus said: “An important task in primary mathematics teaching is to develop students 'computing power.” But from the actual situation in primary schools, students' computing power is still very poor, specifically in many students Mathematical rules, nature, the law of use is not flexible enough, the calculation process cumbersome, slow, the correct rate is not high enough. How to change this situation,
