2026秋北师大六上数学核心素养教案课件

北师大六上数学｜身高的情况，怎么上不枯燥|||📊北师大六上数学｜《身高的情况》备课笔记
第九单元数据处理，很多新老师容易上成单纯画图课。

✅本课教材特点
▪真实情境：班级学生身高原始数据，数据量大、杂乱
▪完整统计流程：**原始数据→分段整理→填统计表→绘制条形统计图→分析解读数据**
▪核心技能：学会分段分组，用正字法统计每一段人数
▪素养目标：发展数据分析观念，读懂图表背后信息

💡教学重点

1. 理解为什么要分段：原始数据太多，分段后方便观察分布
2. 掌握分段整理数据的方法，不重复、不遗漏
3. 根据统计表绘制条形统计图
4. 读图分析：哪个身高段人数最多、最少，判断个体所处位置

⚠️教学难点
理解**分段标准的意义**，明白分段是为了解决实际问题。

✨课堂小建议

1. 可以拿班级真实身高做课堂活动，代入感更强
2. 强调统计过程，不要只盯着画图结果
3. 多提问：从图表你读到哪些信息？能得到什么结论？

统计课，重在让孩子体会数据的价值✨
