“看图找关系”是北师大版六年级上册第83~84页“数学好玩”单元中的一个数学活动,本节课的教学是借助学生已有的折线统计图的知识,正确描述图所表示的事件或行为,并通过研究两个相关联的变量之间的关系,提高观察分析能力,同时渗透一定的函数思想。但“看图找关系”又与折线统计图有所区别,它是对两个相关联的量的一种直观刻画,需要学生关注的是横轴与纵轴所表示的两个量之间的关系,然后根据线的变化发现两个相关联的量的变化过程和规律。
“Look at the map to find the relationship ” is a mathematical activity in the sixth grade of the Beijing Normal University version on the first 83 ~ 84 “math fun ” unit, the teaching of this lesson is based on the knowledge of students’ existing line chart , Correctly describe the events or behaviors represented in the graph, and improve the ability of observation and analysis by studying the relationship between two related variables while infiltrating certain functional ideas. But the “look at the relationship between the map” and the line chart is different, it is an intuitive description of the amount of the two associated, the students need to focus on the horizontal axis and the vertical axis of the two quantities Then, according to the change of line, we found the process and law of the change of two related quantities.
