对于小学低年级学生来说,“学”、“练”、“用”是数学学习中的必要步骤。而“练”作为中间环节,是这些低年级学生巩固“学”、拓展“用”的关键,在小学数学教学中占有重要地位,在课时安排中也占有较大比重。本文根据教学实践,从巩固学生基础数学知识,提高学生数学素养的角度,对小学低年级数学练习设计进行探讨分析,提出练习设计的有效途径。 For elementary school students, “learning”, “practice”, “use” is a necessary step in maths learning. The middle part of the “middle class” is the key for these junior students to consolidate “learning ” and expand “use ”. They occupy an important position in the elementary mathematics teaching and also occupy a large proportion in the class schedule. According to the teaching practice, from the perspective of consolidating students ’basic mathematics knowledge and improving students’ mathematical accomplishment, this paper analyzes and discusses the mathematics practice design of the lower grades in primary schools and puts forward effective ways to practice the exercises.
