简便运算是计算教学的重要组成部分,它是训练学生快速计算能力的主要途径之一。但在实际教学中,很明显可以用简便方法计算的习题,学生做起来却那么的困难,学生在一大堆运算定律中迷失了方向。本文通过“凑整”在教学中地有效渗透优化教学过程,算用结合、强化计算练习的训练以及在计算上寻求学生的个性发展等几方面来提升学生的简便运算能力,让学生感受到简便运算其实很简单,并爱上简算,从而整体提高学生的计算能力、计算速度,有效地培养学生思维的灵活性和创造性。
Simple calculation is an important part of calculation teaching. It is one of the main ways to train students’ rapid calculation ability. However, in practical teaching, it is obvious that exercises can be calculated in a simple way. However, students are so difficult to handle. Students lose their way in the laws of computation. In this paper, students’ sense of convenience is improved through the effective penetration and optimization of teaching process, the combination of arithmetic and computation, the training of computational exercises and the individual personality development of students in computation. To the simple operation is actually very simple, and fell in love with the simple calculation, so as to improve the overall computing power of students, calculate the speed and effectively develop the students thinking flexibility and creativity.
