测量与绘制长度
Measuring & Plotting Lengths
测量长度（精确到最接近的整单位），生成测量数据，并在数轴图上展示这些数据。
Generate measurement data by measuring lengths to the nearest whole unit and display the data on a line plot
学习证据 / Evidence
- 测量几个物体的长度并记录数据
- 绘制数轴图，水平刻度用整数单位标出
- 解读数轴图，回答与数据有关的问题
- Measure the lengths of several objects and record the data
- Create a line plot with a horizontal scale marked in whole-number units
- Interpret a line plot to answer questions about the data
评估问题 / Assessment
如果{{name}}量出十片树叶的长度，精确到最接近的厘米并记录结果，那么{{name}}能否在一张简单的数轴图上展示这些数据，把相同长度的树叶归在一起？
If {{name}} measures the length of ten leaves to the nearest cm and records the results, can they display the data on a simple number-line plot — grouping leaves of the same length?
