找出应用题中的等量关系,是列方程解应用题的关键。根据小学数学教材与学生的认识水平,我注意从以下四个方面引导学生找应用题中的等量关系,布列方程。一、抓住关键词语,揭示等量关系,布列方程在教学中,我们引导学生在认真审题,理解题意的基础上,抓住关键词语,揭示等量关系,布列方程。例如,“小华的身高是160厘米,比小兰高15厘米。小兰的身高是多少厘米?”在引导学生深刻理解题意的基础上,我们可以提出以下问题,帮助学生抓住关键词语,找出等量关系,布列方程。“题中小华身高160厘米比小兰高15厘米,你是如何理
To find out the equivalent relationship in the application problem is the key to solve the column equation solution. According to elementary mathematics textbooks and students' level of awareness, I pay attention to the following four aspects to guide students to find the equivalent relationship in the application problem, the Brent equation. First, to seize the key words, to reveal the relationship between equal, Buple equation in teaching, we guide students to seriously review questions, understand the questions on the basis of the key words to reveal the same amount of relations, Bourgeois equation. For example, “Xiao Hua's height is 160 centimeters, 15 centimeters higher than Xiaolan.Little blue's height is how many centimeters?” In guiding students to deeply understand the questions, we can ask the following questions to help students grasp the key words , Find the same amount of relations, Balakrishnan equation. The title of Xiaohua 160 centimeters tall than the small blue 15 cm, how do you manage
