在小学数学教学中,新授内容结束后,教师必须设计课堂练习,课堂练习不仅是检查学生对新知识掌握情况的重要环节,而且是学生对新知识复习巩固、熟练掌握、形成技能、不断创新的重要手段,因此,设计好课堂练习是每一名数学教师的必修课。多年的小学数学教学实践使我认识到:设计数学课堂练习应体现“四性”。由浅入深,体现层次性。数学知识与其他学科知识有所不同,逻辑性比较强,设计课堂练习时,要遵循数学知识的编排体 In the elementary mathematics teaching, after the content of the new teaching is over, the teacher must design the classroom practice. The practice of the classroom is not only an important part of examining students’ mastery of new knowledge, but also the students reviewing, consolidating, mastering, forming skills and innovating new knowledge Therefore, designing a good classroom practice is a required course for every math teacher. Many years of primary school mathematics teaching practice made me realize that the practice of designing mathematics classroom should embody “four characters ”. From shallow to deep, reflecting the level. Mathematical knowledge and other subject knowledge is different, more logical, the design of classroom practice, we must follow the mathematical knowledge of the body
