角的度量
Measuring angles
使用量角器测量整度数的角；会画指定度数的角，并能画出给定大小的角。
Measure angles in whole-number degrees using a protractor; draw given angles and sketch angles of specified measure
学习证据 / Evidence
- 用量角器测量一个角，读数为47°
- 用量角器画一个135°的角
- 判断用量角器量钝角时应该看哪一圈刻度
- Measure an angle with a protractor and read 47°
- Draw an angle of 135° using a protractor
- Identify which scale on the protractor to use for an obtuse angle
评估问题 / Assessment
如果给 {{name}} 一个量角器和一个画在纸上的角，{{name}} 能否准确测量这个角，然后画出一个你指定度数的角？
If {{name}} is given a protractor and an angle drawn on paper, can they measure it accurately and then draw a new angle of a size you specify?
