《单式折线统计图》是小学数学苏教版义务教育课程标准实验教科书四年级(下册)的内容,通过与学生熟悉的现实生活中实际经验联系,让学生学会看折线统计图,在观察与对比后,能根据统计图得到自己需要的信息,并对图中的信息进行简单地分析,回答简单的问题,知晓折线统计图与条形统计图的区别,感受折线统计图在表示数据变化趋势方面的作用,能够依据数据变化的特点进行合理的判断与预测,培养学生统计素养,激发学生学习数学的兴趣,从中获得价值体验。
The “Single Line Polyline Chart” is the content of the fourth grade (the second volume) of the compulsory education curriculum standard experimental textbook for primary school mathematics. Through the practical experience familiar with the students, we can let the students learn to see the broken line chart, And contrast, can get the information they need according to the chart, and simple analysis of the information in the diagram, answer simple questions, know the difference between the line chart and the bar chart, feel the line chart changes in that data The role of the trend can be based on the characteristics of data changes to make reasonable judgments and forecasts, training students in statistical literacy, stimulate students interest in learning mathematics, to gain value from experience.
