对于小学生来说计算能力的培养是在小学数学教学中的一项重要任务。教学大纲里要求学生在计算能力方面达到“会”“比较熟练”“熟练”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 The training of computational skills for primary school students is an important task in elementary mathematics teaching. In the syllabus, students are required to achieve three levels of “meeting”, “being familiar”, “proficiency” in terms of computing power, and “three main” and “three” Not more than "the explicit provisions. So, how to strengthen the calculation of teaching
