练习是课堂教学的有机组成部分,是学生掌握知识、形成技能、发展智力的重要手段。要灵活处理好教材资源开发与拓展之间的关系,精心设计适应不同程度学生发展需要的习题,突出习题的层次性、针对性、思考性和开放性。本文从两个方面谈一谈小学数学课堂练习设计,一是新授课之后的练习设计,二是单元复习课的练习设计。 Exercises are an integral part of classroom teaching and an important means for students to master knowledge, form skills and develop intelligence. We should flexibly handle the relationship between the development and expansion of teaching resources, carefully designed exercises to meet the needs of different levels of students’ development, and emphasized the level, relevance, thinking and openness of exercises. This article from two aspects talk about the primary school mathematics classroom practice design, one is the new lectures after the practice design, the second is unit review exercises design.
