用立体图形搭建

组合立体图形（正方体、长方体、圆锥、圆柱）并创作复合图形；用基本图形搭出新图形。

Compose three-dimensional shapes (cubes, right rectangular prisms, right circular cones, right circular cylinders) and create composite shapes; build new shapes from component shapes

学习证据 / Evidence

• 堆叠正方体和长方体来搭建塔或建筑物。
• 组合立体图形做成一个新的立体（例如把圆锥放在圆柱上面）。
• 描述一个组合立体图形是由哪些基本立体图形组成的。

• Stack cubes and prisms to build towers or structures
• Combine 3-D shapes to make a new solid (e.g. cone on top of cylinder)
• Describe a composite 3-D shape in terms of its component shapes
