Select three-dimensional shapes
Key notes:
- What are Three-Dimensional Shapes?
- 3D shapes have length, width, and height.
- They are also called solid shapes.
- You can touch, hold, and see them from all sides.
🔶 Common 3D Shapes and Their Real-Life Examples:
| Shape | Name | Real-Life Example |
|---|---|---|
| 🟦 Cube | Cube | Dice, Gift box |
| 🔵 Sphere | Sphere | Ball, Orange |
| 🟫 Cylinder | Cylinder | Can, Battery |
| 🟥 Cone | Cone | Ice cream cone, Party hat |
| 🟩 Rectangular Prism | Cuboid | Book, Brick |
✏️ How to Select 3D Shapes:
- Look at the shape’s faces, edges, and corners.
- Match it with real-world objects.
- Use simple words like “box-shaped,” “ball-shaped,” “can-shaped” to help describe.
🔍 Tips for Students:
- A cube has 6 equal square faces.
- A sphere has no edges or corners—it’s completely round.
- A cylinder has 2 flat circular faces and 1 curved surface.
- A cone has 1 flat circular face and a point (vertex).
- A rectangular prism has 6 faces, but not all are squares.
