计算教学在小学数学教学中占有很大的比例,只看中年级教材,单纯的计算教学就占30%以上。另外,数学知识的学习几乎都离不开计算,所以在小学阶段打好计算基础并形成计算能力,必会为其日后学习乃至终身发展产生深远影响。那么,如何切实提高计算教学的有效性,使计算教学达到高效低耗呢?下面谈谈笔者对小学中年级数学计算教学的一些粗浅认识。一、创设情境,体会计算的现实意义计算是为解决生活中的具体问题而服务的,只有 Calculation of teaching in primary school mathematics teaching occupy a large proportion, only middle school textbooks, simple calculation of teaching accounted for more than 30%. In addition, almost all mathematical knowledge can not be separated from calculation. Therefore, laying the foundation for calculation and forming computational skills in primary school will certainly have a far-reaching impact on their future learning and lifelong development. So, how to effectively improve the effectiveness of computational teaching so that computational teaching to achieve high efficiency and low consumption? Here to talk about the author of primary school mathematics teaching in mathematics some superficial understanding. First, create a situation, realize the practical significance of calculation Calculation is to solve the specific problems in life and service, and only
