三维图形（10岁以上）
3-D shapes (age 10+)
认识、描述并制作简单的三维图形，包括制作展开图。
Recognise, describe, and build simple 3-D shapes, including making nets
学习证据 / Evidence
- 判断哪个展开图能折成给定的三维图形
- 制作一个三棱柱的展开图并折叠验证
- 通过说出一个三维图形的面、棱和顶点来描述它
- Identify which net will fold into a given 3-D shape
- Construct the net of a triangular prism and fold it to verify
- Describe a 3-D shape by naming its faces, edges, and vertices
评估问题 / Assessment
如果给{{name}}一张扁平的十字形卡纸（展开图），{{name}}能否预测它折叠后会变成什么三维图形，并动手折一折来验证？
If {{name}} is given a flat cross-shaped piece of card (a net), can they predict what 3-D shape it will make when folded up — and then fold it to check?
