练习课历来是教学中一个重要的组成部分,特别是在小学数学教学中,练习的比重约占整个教学时数的三分之一,抓好小学数学练习的教学效益,对于及时巩固和深化刚刚学习的新知识,提高学生的数学素养,有着不可低估的价值。但在现实中,学生没有获取知识的新鲜感,学习起来热情相对降低。老师对小学数学练习的目的、形式、效果等现实 Practice has always been an important part of teaching, especially in primary school mathematics teaching, practice accounted for about one-third of the total teaching hours, do a good job in primary school mathematics teaching effectiveness, in order to consolidate and deepen the just Learn new knowledge and improve students’ mathematical quality, with the value can not be underestimated. However, in reality, students do not have the freshness of acquiring knowledge, and learning enthusiasm is relatively reduced. The purpose of the teacher in primary school mathematics exercises, forms, effects and other realities
