数学课程标准的基本理念指出:“数学教育要面向全体学生,适应学生个性发展的需要,使得人人都能获得良好的数学教育,不同的人在数学上得到不同的发展。”小学阶段,受到身心发展规律的制约,学生很难在短时间内了解老师所讲授的所有相关知识点。即使通过课后慢慢探究,也不能保证每个学生做到灵活运用的程度。所以应该用心设计一些课堂练习,让学生通过练习了解数学概念、法则、规律等等,课堂练习的意义也就在此。然而在实际数学教学过程
The basic idea of mathematics curriculum standards states: “Mathematics education should be geared to all students and meet the needs of individual personality development so that everyone can have a good math education and different people get different developments in mathematics.” "Primary school , Subject to the laws of physical and mental development constraints, students find it difficult to understand in a short time the teacher taught all the relevant knowledge points. Even after studying slowly through the class, can not guarantee that each student to be flexible use of the degree. Therefore, we should carefully design some classroom exercises, so that students can understand the mathematical concepts, laws, rules and so on through practice, and the meaning of classroom practice is also here. However in the actual mathematics teaching process
