小学生计算能力的培养是小学数学教学的一项重要任务。教学大纲要求学生在计算能力方面达到“熟练”、“比较熟练”、“会”三个层次,在计算的范围上做了“四个为主”和“三个不超过”的明确规定。那么,如何加强计算教学,提高计算能力呢?一、严格教学要求是前提教学大纲在计算教学上要求达到三个层次,具体地说,就是根据每一部分所占的地位、作用区别对待,对一位数的加减法、表内乘除法等最重要的口算要求达到熟练;对于除此以外的基本口算,万以内的加减法和用一两
The training of primary students’ computing ability is an important task in primary school mathematics teaching. The syllabus requires students to achieve three levels of “proficiency”, “more proficiency” and “fairness” in terms of computing power, and “four main” and “three” A no more than "the explicit provisions. So, how to strengthen the calculation of teaching, improve the computing power? First, the strict teaching requirements is the premise of the teaching syllabus in computing requirements to achieve three levels, specifically, is based on the status of each part, the role of discrimination, Addition and subtraction of digits, table multiplication and division and other the most important port count requirements to achieve proficiency; for other than the basic port count, within plus or minus million plus one or two
