计算,是开启小学数学大门的钥匙,是小学数学的灵魂和根本。九年义务教育小学数学教材中,口算练习从一年级10以内的加、减法至六年级分数、小数四则混合运算,几乎遍布每个练习,而且,课后还有专门的口算卡,这足以证明:加强口算训练是小学数学改革的一个重要趋势。前不久,我校低段学生举行了一次口算比赛,结果是平均每分钟只能做5、6道题,和前几年学生的口算能力相差甚大。之后,我们又向其他学校的老师打听
Calculation, is the key to open the door to primary mathematics, is the soul and primary school mathematics. Nine years of compulsory education in primary school mathematics textbooks, oral exercises from the first grade plus or minus 10 to the sixth grade scores, the decimal four mixed operations, almost every practice, and after class there are special Miaojian card, which is sufficient to prove : Strengthening oral arithmetic training is an important trend in primary school mathematics reform. Not long ago, a low-income student in my school held a word-of-mouth contest, which resulted in an average of only 5 or 6 questions a minute. After that, we asked the other school teachers again
