练习是课堂教学的的组成部分,是学生学习的重要环节,是巩固知识、形成技能、发展思维、挖掘潜能的有效手段。新课改背景下,小学数学课堂练习设计既不能走单调重复的老套路,又不能一味求新哗众取宠偏离学科中心,要确保练习设计为有效教学服务,让学生通过练习实现“知识与技能”、“过程与方法”、“情感、态度、价值观”的综合提升和发展。下面,笔者结合教学实践,谈谈对小学数学课堂练 Exercises are an integral part of classroom teaching, an important part of students' learning, and an effective means to consolidate knowledge, form skills, develop thinking and tap potential. Under the background of the new curriculum reform, primary school mathematics classroom practice design can neither take the monotonous repetition of the old routine, but also can not blindly seek grandstanding deviate from the discipline center, to ensure that the practice design is an effective teaching service, so that students can practice through “knowledge and skills ”,“ Process and Method ”,“ Emotion, Attitude, Values ​​”and overall improvement and development. Next, I combine teaching practice, talk about the primary school mathematics classroom practice
