Three-Dimensional Figures

Sphere

cube

Square Pyramid

Cone

Cylinder

Rectangular Prism

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

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

Box 2:

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

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

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

Solid Shapes

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

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

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.

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.

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.

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.

Now it’s your turn! You will see a chart from last year’s 6th grade math class on how well they did on the questions that followed this three-dimensional figures powerpoint presentation

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

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.
