数学知识的学习几乎都离不开计算,计算是小学生必须掌握的一项很重要的基本技能,也是学生后续学习的基础,同时计算教学也担负着数学课程所承担的其他任务。计算教学不仅要使学生能够正确地进行四则运算,还要求学生能够根据数据的特点,恰当地运用运算定律和运算性质,选择合理灵活的计算方法和计算过程使计算简便。计算是由于解决生产、生活
Almost all of the study of mathematical knowledge can not be separated from calculation. Calculation is an important basic skill that pupils must master. It is also the basis of follow-up study of students. At the same time, calculation teaching also takes on other tasks undertaken by mathematics courses. The teaching of calculation not only needs students to carry on the four arithmetic correctly, but also requires the students to make use of the law of calculation and the nature of the operation properly according to the characteristics of the data. Choosing a reasonable and flexible calculation method and calculation process makes the calculation easy. Calculation is due to solve the production, life
