计算在小学生的数学学习中占有重要地位,计算的速度与准确率也将直接影响到学生最终的成绩,通常计算不准确的学生是很难取得优秀成绩的。面对学生计算的错误,很多人都会认为是马虎造成的,那么真的只是马虎吗?马虎的背后其实是算理不通,只是机械运用算法,这样就难免会出现错误。下面我结合小学《数学》北师大版“蚂蚁做操”这节计算课,来谈谈如何上好一节计算课。
Calculation plays an important role in pupil’s mathematics learning. The calculation speed and accuracy will also directly affect students’ final grade. It is very difficult to calculate the inaccurate students usually. In the face of mistakes made by students, many people think that it is sloppy. Is it really sloppy? Behind the sloppy fact is that the mechanics are not applied, but the mechanical algorithm is used. This will inevitably lead to mistakes. Now I combine elementary “math” Beijing Normal University version “ant do exercises ” this section of the calculation class to talk about how to better a section of the calculation class.
