计算是小学数学教学的重要内容,它贯穿于小学数学教学的始终,无论是数学概念的形成、数学结论的获得、还是数学问题的解决等都依赖于计算活动的参与。因此培养学生计算能力是小学数学教学的一项重要任务。而传统的小学计算教学常常通过机械重复、大量题目的训练,只重视计算的结果,不重视计算法则的形成过程和计算方法的概括。在课改初期,教师们认识到了原有教学模式的局限,在计算教学中又过分强调计算方法的多样化,教师没有起到很好的主导作用, Computation is an important part of mathematics teaching in primary schools. It runs through the teaching of mathematics in elementary schools. Whether it is the formation of mathematical concepts, the acquisition of mathematical conclusions, or the solution of mathematical problems, computation relies on the participation of computational activities. Therefore, training students in computing power is an important task in primary school mathematics teaching. However, the traditional teaching of primary calculation often through mechanical repetition, a large number of topics of training, only pay attention to the results of the calculation, does not attach importance to the formation of calculation rules and calculation methods. In the early stages of curriculum reform, teachers recognized the limitations of the original teaching mode, and emphasized too much on calculation methods in computing teaching. Teachers did not play a very good leading role,
