初中数学一元一次方程教材内容学完后,可以发现,许多实际问题可以通过列方程得到解答,而在解答过程中,思考问题的出发点不同,往往就得到不同的解答方法,通过对比,可以从中选择较优的解题方案,有利于开阔学生的思维空间,丰富学生的想象力,提高学生分析问题和解决问题的能力.案例1在一节练习课上,教师请三个学生在黑板上各自完成一道数学题:已知5台A型机器一天生产的产品装满8箱后还剩4个,7台B型机器一天生产的产品装满11箱后还剩1个,每台A型机器比B型机器一天多生产1个产品,求每箱有多少个产品?
After learning the text content of the elementary mathematics equation in junior high school, you can see that many practical problems can be solved by the column equation. In the process of answering the questions, the starting points for thinking are different, and different solutions are often obtained. By comparison, you can choose from The better solution is conducive to broaden students’ thinking space, enrich students’ imagination and improve students’ ability to analyze and solve problems Case 1 In a practice class, teachers invited three students to complete their work on the blackboard A math problem: Five A-type machines are known. One day after the 8-box is filled with 4 products, there are 4 left. Seven B-type machines produce 1 product after they have been filled in a day. B-type machines produce more than one product a day, how many products per box?
