一、复习铺垫,引入新课1.师:什么是方程?列一个方程要具备几个条件?(1含有未知数;2等式)2.口算:8x=240 x+40=60 x÷4=122x=20 x-3.2=1.8 4x=100师:大家掌握的很好,这节课我们继续学习有关方程的知识。(揭示课题《列方程解决问题》)评析开门见山地快速切入课题。通过复习内容既回顾了上节课所学的知识,更重要的是通过复习进一步熟练应用本节课所要用到的基础知 First, review the bedding, the introduction of a new lesson 1 division: What is the equation? Listed an equation to have a few conditions? (1 contains unknowns; 2 equation) 2 Mouth: 8x = 240x40 = 60x ÷ 4 = 122x = 20 x-3.2 = 1.8 4x = 100 division: we master well, this lesson we continue to learn about equations. (Reveal the subject of “column equation to solve the problem”) Evaluation quick to cut into the topic. By reviewing the contents of the review both the knowledge learned in the previous lesson, but more importantly, through the review to further proficiency in the basic knowledge used in this lesson
