计算是小学数学的一个重要组成部分,有效地提高小学生的数学计算的正确率是小学数学教学的一个关键环节。考虑到小学生的年龄、心理特点和认知能力,他们比较容易对枯燥乏味的数学计算失去兴趣,对计算敷衍了事,不认真去做,正确率自然就变低了。在小学数学教学过程中,我发现存在的一些问题:小学生的口算水平有待提高,基础的计算掌握的还不够,计算法则有些混乱等。这对学生数学基本计算技能的影响很大,不利于学生思维能力的形成。对此,我在 Calculation is an important part of elementary mathematics. Improving the accuracy of primary mathematics is an essential part of primary mathematics teaching. Taking into account the age, psychological characteristics and cognitive abilities of primary school students, they are more likely to lose interest in dull mathematical calculations. When they calculate perfunctoryly and do not do it seriously, the correct rate will naturally become lower. In primary school mathematics teaching process, I found that there are some problems: the level of pupils should be improved, the basic calculation is not enough, the calculation method is a bit confused and so on. This has a great impact on students ’basic computational skills, which is not conducive to the formation of students’ thinking ability. I am here
