一、计算计算是小学数学教学的主干,它可以分为口算、估算和笔算。计算也是学生在解决数学问题时最常用的一种方法。翻开数学课本上的练习,打开任何一份数学试卷,需要学生动笔计算的比例可以占到90%以上。填空题离不开计算,判断、选择同样也离不开计算,就连解决问题,如果算式列对了,计算错误,也是会留下遗憾的。计算为学生的判断和选
First, the calculation and calculation is the backbone of primary mathematics teaching, it can be divided into port count, estimation and pen calculation. Calculation is also one of the most commonly used methods for solving mathematical problems. Opened math textbook exercises, open any mathematical papers, students need to calculate the proportion of pen can account for more than 90%. Fill in the blank can not be separated without calculation, judgment, choice also can not be separated from the calculation, and even solve the problem, if the formula is right, the calculation error, it will leave regret. Calculated as a student’s judgment and choice
