课堂练习是小学数学教学活动的基本环节,是学生巩固新知识、形成技能、培养能力、教学反馈与教学调控的重要途径。练习设计的好坏,直接影响到学生的学习效果。练习的设计既要注重教学重点、难点的突破,又要在原有的知识基础上有所提高;既要面向全体,又要照顾到学生的个别差异。因此,课堂练习的设计必须有层次性,使每一位学生在不同层次上都有不同程度的提高。
Classroom practice is the basic link of elementary mathematics teaching activities, which is an important way for students to consolidate new knowledge, form skills, training ability, teaching feedback and teaching control. Good or bad practice design, a direct impact on student learning. The design of practice should not only pay attention to the breakthrough of teaching emphasis and difficulty, but also improve on the basis of the original knowledge. It should not only be for the whole group but also take care of individual differences of students. Therefore, the design of classroom practice must be hierarchical, so that each student has different levels of improvement at different levels.
