随着社会的发展,数学计算在社会生活各方面越来越显示出重要的作用。为了跟上时代的步伐,我们把计算教学贯穿在小学数学教学的全过程中,这也就使得计算教学变成了小学数学教学的“重头戏”。所以新课标对计算也提出了新的要求,它不仅要求计算正确,迅速,更突出计算方法是否合理,简便,灵活,注重口算,笔算,估算等多种方法的有机结合,使学生在使用各种计算方法的实践中逐步提高计算能力。但是在教学实践中,我们发现小学生计算能力现状不容乐观,因此本文试图通
With the development of society, mathematical calculations have increasingly shown an important role in all aspects of social life. In order to keep up with the pace of the times, we put computational teaching through the whole process of elementary mathematics teaching, which also makes computing teaching become the “main event” of elementary mathematics teaching. Therefore, the new curriculum also put forward new requirements for calculation, which not only requires the calculation is correct, rapid, more prominent calculation method is reasonable, simple and flexible, pay attention to port count, pen calculation, estimation and other methods of organic combination so that students use The practice of various calculation methods gradually improve the computing power. However, in teaching practice, we find that the current situation of pupils’ computing abilities is not optimistic. Therefore,
