Introduction 3D shapes

Introduction of 3D shapes/Solid Shapes for primary 6 Students
Hope it will be help the students to learn about the 3D shapes

1. 3D shapes Welcome To The Fascinating World Of 3D Shapes

2. Names of 3D shapes Cube cylinder Sphere Cone Rectangular Prism Square based pyramid Cuboid Triangular based pyramid Triangular prism

3. Our Topic Of Discussion Cube. Cylinder. Sphere. Prism. Pyramid.

4. 3D Shapes 3D shapes can be solid or hollow. 3D Shapes has 3 dimension: Length. Width. Height.

5. Now Some Technical Terms To Address 3D Shapes Surface. Face. Base. Edge. Corner Vertex (singular)/Vertices (plural)

6. Surface The curved part of a 3D shape . Eg : Cylinder & Cone Surface

7. Face Part of a 3D shape that is flat .

8. Base The bottom face of a 3D object. Base

9. Edge The line where two faces meet on a 3D object. 6 Edges 5 Edges

10. Corner The point where three or more edges touch. This cube has 12 corners all together.

11. Vertex (Vertices) The point where three or more edges meet. This cube has 12 vertices all together.

12. Cube A three-dimensional shape which has: 6 F aces (All are of the same size) 12 E dges 8 C orners/ V ertex edge vertex face

13. Cylinder A three-dimensional shape which has: 2 F aces 1 S urface E dges C orners / V ertex face face Surface

14. Sphere A three-dimensional shape which has : F aces 1 S urface E dges C orner / V ertex Surface

15. There are different types of prisms and they are based on the shape of its bases : R ectangular Prisms S quare Prisms T riangular Prisms H exagonal Prisms Prism

16. Pyramids There are different types of pyramid and they are based on the shape of its bases: Have 1 base. Have Triangular side faces that meet at one Vertex. Examples: Square Pyramid, Triangular Pyramid, Rectangular pyramid etc. base Triangular face

17. Square Pyramid A three-dimensional shape which has: 5 F aces (1 square and 4 triangles) 8 E dges 5 C orner / V ertex

18. Rectangular Pyramid A three-dimensional shape which has: 5 F aces (1 Rectangular + 4 Triangles) 8 E dges 5 C orner / V ertex Rectangular face Triangular face

19. Prism Vs Pyramid PRISM -At least 3 Faces that are Rectangles . - Two congruent faces on top and bottom called bases . -The shape of the base determines what type of prism the figure is. PYRAMID -At least 3 Faces that are Triangles . - One base . - The shape of the base determines what type of prism the figure is.
