低年级计算教学的内容是整数计算教学中最基础的内容,它是多位数计算教学的基础,也是分数、小数计算教学的基础。因此,小学低年级计算教学是后续计算教学的基础。本文针对于新课标背景下低年级计算教学出现的部分问题,着重计算学习中的情境创设、算法探究交流以及处理算理与算法的关系三方面进行了教学策略的新思考。 The content of teaching in the lower grades is the most basic content in the teaching of integer calculation. It is the basis of multi-digit calculation teaching and also the basis of fractional and decimal calculation teaching. Therefore, the calculation of teaching in the lower grades of primary school is the basis for the subsequent calculation of teaching. In this paper, some new problems in the teaching of lower grades in the new curriculum are pointed out, and the new thinking of teaching strategies is put forward in three aspects: setting up situations in computational learning, exploring and communicating algorithms, and dealing with the relationship between algorithms and algorithms.
