二分之一和四分之一（8岁以上）
Halves and quarters (age 8+)
通过测量长度生成测量数据，测量结果精确到最接近的半英寸或四分之一英寸；在数轴图上展示这些数据，数轴刻度用整数、半英寸和四分之一英寸标出。
Generate measurement data by measuring lengths to the nearest half and quarter inch; display the data on a line plot with a scale marked in whole numbers, halves, and quarters
学习证据 / Evidence
- 测量五个物体，精确到最接近的四分之一英寸。
- 制作一张数轴图，用半英寸为单位展示同学们铅笔的长度。
- 读数轴图，并回答与数据相关的问题。
- Measure five objects to the nearest 1/4 inch
- Create a line plot showing the lengths of classmates' pencils in half-inches
- Read a line plot and answer questions about the data
评估问题 / Assessment
如果{{name}}测量十支铅笔的长度，精确到最接近的四分之一英寸，能否记录这些数据并绘制在一张按四分之一英寸刻度划分的数轴图上，然后找出出现次数最多的长度？
If {{name}} measures ten pencil lengths to the nearest quarter inch, can they record the data and plot it on a number line split into quarters — then spot which length appears most?
