小学数学教学的一项重要任务是培养学生的计算能力,要求计算正确、迅速,方法合理、灵活。怎样完成这个任务,逐步达到教学要求呢?我们的体会是: 一、只有讲清基础知识,才能使学生获得正确运算的能力。 小学数学中的概念、性质、法则、公式等,都是基础知识,必须使学生切实学好。建立清晰的概念,是学生牢固地掌握知识的基础,也是正确地进行运算的先决条件。教师要舍得下功夫讲清基本概念。例如“分数单位”这个重要的
An important task in primary school mathematics teaching is to develop students' computing abilities, requiring the calculation to be correct, rapid, reasonable and flexible. How to accomplish this task, and gradually meet the teaching requirements? Our experience is: First, only to clarify the basics in order to enable students to get the correct computing power. The concept, nature, rules and formulas in elementary mathematics are all basic knowledge, and students must learn effectively. Establishing a clear concept is the foundation on which students have a firm grasp of knowledge and is also a prerequisite for proper operation. Teachers should be willing to make effort to clarify the basic concepts. For example, “fractional unit” is important
