课堂练习要针对不同学生,设计适合于不同层次的练习题,习题安排应从易到难,形成梯度,符合学生的认知规律,使全体学生都能得到不同程度的提高,让不同层次学生都有体会成功的机会。所以,小学数学课堂练习要遵循循序渐进的原则,要讲究层次性。 Class exercises for different students, design suitable for different levels of exercises, exercises should be easy to difficult to form a gradient, in line with the cognitive laws of students, so that all students can be improved to varying degrees, so that students at different levels have Experience the chance of success. Therefore, elementary mathematics classroom practice to follow the principle of gradual and orderly, to pay attention to the level of.
