1. Solids: Three – Dimensional figures EQ: How do you identify various three-dimensional figures? How do you distinguish between prisms and pyramids? 6.G.4

2. What are three-dimensional figures? A three- dimensional figure encloses a part of space. In other words it can hold something (water, air, etc.)

3. Two main types of 3-D Figures PrismPyramid Both Has at least three faces that are rectangles Has two congruent faces on the top and bottom called bases The shape of the base tells what type of prism the figure is Has at least three faces that are triangles Has only one base

4. Features of a 3-D figure Faces Edge Vertex Edge- formed by two faces of a 3-D figure sharing a side Vertex (plural:vertices)- the point at which three or more edges meet Face- the flat surface of a figure Base- the flat end/bottom of a surface Bases

5. Identify the number of faces, edges, and vertices on each three-dimensional figure. A. B. 4 faces8 edges5 vertices7 faces15 edges10 vertices1 Base2 Bases

7. Prisms Rectangular Prism Pentagonal Prism

8. Pyramids Square Pyramid Triangular Pyramid

9. Other 3-D Figures Cone- is a figure like a pyramid, but has a circular base and a curved surface

10. Other 3-D Figures Cylinder- a curved figure with two circular bases

11. Other 3-D Figures Sphere- a 3-D figure with no faces, bases, edges, or vertices

12. Let’s Play Name that Figure!

13. Cylinder

14. Triangular Prism

15. Cube

16. Square Pyramid

17. Okay…this last one is hard…Ready??

18. Pentagonal Pyramid

19. Polyhedron A 3-dimensional figure that has polygons as faces Polygons must have straight lines! PolyhedronsNot Polyhedrons
