练习是学生形成技能技巧的基本途径,教师要精心设计每节课的练习内容和练习的方式方法。 1.练习内容要循序渐进 每节课都要围绕数学重点精心设计单项练、基本练、综合练、发展练。单项练主要是进行口算或回答,以口算提高学生的速算能力,以口答着重训练学生说理和表达思路。基本练是以习题为主要内容的促进技 Practice is the basic way for students to develop skills and skills. Teachers should carefully design the contents of each lesson and the ways and means of practice. 1. Exercise should be gradual Each lesson should be carefully designed around the mathematical focus of a single practice, basic training, comprehensive training, development practice. Individual training is mainly carried out mouth calculation or answer, in order to improve the speed of calculation of the student's ability to respond to the mouth to stress training and expression of ideas. The basic training is based on exercises as the main content of the promotion of technology
