计算是人们在日常生活中应用最多的数学知识之一,是小学数学教学的基石。以往对学生计算重点要求计算方法与速度。新课标对计算教学提出了新要求,不仅要求学生掌握计算方法,保证计算速度,更要求学生能够恰当合理地在口算、笔算、估算等多种计算方法中灵活选择、有机结合。但在近几年的教学实践中,学生不仅计算速度慢,正确率低下,而且不能灵活选择做题方法。因此,计算教学绝不容忽视。
Computation is one of the most used mathematical knowledge in daily life. It is the cornerstone of elementary mathematics teaching. In the past, students calculated the key requirements calculation method and speed. The new curriculum standards put forward new requirements for teaching. It not only requires students to master the calculation methods and ensure the calculation speed, but also requires the students to be able to flexibly choose and combine organically and rationally in a variety of calculation methods such as calculating, calculating and estimating. However, in the teaching practice in recent years, students not only calculate the speed is slow, the correct rate is low, but also can not flexibly choose to do the problem method. Therefore, the calculation of teaching must not be ignored.
