贯通小学数学计算算理学习路径

Having a Thorough Knowledge of the Approach to Primary School Mathematics Calculations

"运算能力"作为数学十大核心素养之一贯穿小学数学教学全过程。培养小学生运算能力,应将运算融入实际生活情境,引导学生在探索的过程中掌握算法,以孕育数学思想方法 ,实现数学思维的发展。文章从运用直观表征,在情境中明晰算理;注重新旧知识联系,引导自主探究发现算理;多变训练与应用结合,拓展算理思维空间;培养良好习惯,由慢至快完善算理思维等四方面,论述贯通小学数学算理学习路径。

As one of the top ten core qualities of mathematics, "computational ability" runs through the whole process of primary school mathematics teaching. To cultivate primary school students' computing ability, we should integrate the calculations into the real life situations and guide students to master the algorithms in the process of exploration so as to nurture mathematical thinking methods and realize the development of mathematical thinking. This article discusses the approach to having a thorough knowledge of primary school mathematics calculations from such aspects as using visual representations to clarify the calculations in the context; paying attention to the connection of old and new knowledge, and guiding the students to do independent inquiry to discover mathematics calculations;combining mutability training with application to expand the space of mathematical thinking; cultivating good habits to accomplish mathematical thinking gradually.
