课本练习是课程教学结束后学生用以巩固和加强所学内容的习练,但是,课本练习的数量和功用毕竟有效,教师如果指望仅仅用课本内的习题来实现学生对于学过数学知识的巩固加深,让学生可以在完成这些习题后就牢固掌握所学知识,这基本是很难达成的。正是因为如此,我们才需要加强对于小学数学课外习题的开发应用,要以课本为根基,灵活进行习题内容的设计,以有效实现对于课内教学巩固加强的效果。 Textbook practice is the practice of students to consolidate and strengthen the content after the end of the course teaching. However, the quantity and function of textbook practice are effective. Teachers should expect to consolidate the knowledge of mathematics only with the textbooks Deepen, so that students can firmly grasp the knowledge after the completion of these exercises, which is basically difficult to reach. Precisely because of this, we need to strengthen the development and application of extracurricular math problems in primary schools. We should use textbooks as the basis to flexibly design the exercises so as to effectively consolidate and strengthen the effectiveness of intra-curricular teaching.
