7. Rectangular Prism

8. Polygon vs. Polyhedron
POLYGON: A plane shape (two-dimensional) with straight sides. POLYHEDRON: A solid with flat faces (from Greek poly- meaning "many" and -edron meaning "face"). Example: pyramids and prisms

10. Box 1:
3-Dimensional figures are not flat figures. They have length, width, and height.

11. Box 2:

12. A 3D shape with two flat shapes connected by rectangular faces
What is a prism?
A 3D shape with two flat shapes
connected by rectangular faces
Whatever the flat shapes at the end
are determines the type of prism
Triangular
prism

13. A 3D shape with a flat shape as a base and triangular faces
What is a pyramid
A 3D shape with a flat shape
as a base and triangular faces
sloping up to ONE point
What ever the flat shape at the base
is, determines the type of pyramid
Square-based
pyramid

15. Box 3:
Face: Face is a flat surface, typically outside surface of any 2D and or 3D object
Edge: Edge is a line that connects faces together. It is a line where two faces meet.
Vertices: Vertex is a point or corer where edges and or multiple faces meet

17. Box 4: Rectangular prism
face
base
edge
vertex
A rectangular prism has 6 faces, 8 vertices, and
12 edges.

18. Box 5 Cube: face vertex edge
A cube, just like a rectangular prism, has 6 faces (all squares), 8 vertices, and 12 edges.

19. No box: Rectangular Pyramid
A rectangular pyramid has 5 faces. Its base is a rectangle or a square and the other 4 faces are triangles. It has 8 edges and 5 vertices.

20. vertex
No Box
Triangular pyramid
face
base
A triangular pyramid has four faces. All faces,
including its base, are triangles. It has six edges
and four vertices.

21. Box 6: Triangular prism base base face face vertex
A triangular prism has five faces. Its base is a triangle. (Notice that even when the triangular prism sits on a rectangle, the base is still a triangle.) Two of its faces are triangles; three of its faces are rectangles. It has six vertices and nine edges.

22. Box 7: Square pyramid face vertex base
A square pyramid has 5 faces. Its base is a square and the other 4 faces are triangles. It has 8 edges and 5 vertices.

32. Homework
-Glue homework on Page 20 in composition book. -Clear off desk and get ready for the marshmallow lab 

33. Marshmallow Lab
In a group you are going to make 3-D figures that we just went over today in class. Marshmallows-Vertices Toothpicks-Edges After you complete a 3-D figure raise your hand and I will walk over to check.
