A curtain opens to one level to reveal other animated character shapes: a sphere, a cube and a pyramid.
NARRATOR: This is a critical time for the three-dimensional team. And who’s going to win the coveted and absolute prize of, uh. . . most properties?
Two cubes clap their hands as they prepare to compete.
NARRATOR: Well, anyway. . . A three-dimensional die has six faces.
The faces of the dice are lit up to highlight the six. A judgment on write 6 under the faces on a marker. The edges of the dice are now illuminated. Next, the judge writes 12 below the edges, then the corners of the dice are highlighted, and 8 is written below the vertices.
NARRATOR: Edges – that’s twelve. Okay, so what about the corners or vertices: are they the elements where the edges meet?Eight!
The cubes greet each other to the applause of the crowd.
NARRATOR: Oh, dice are awesome! It’s time for the mighty square-based pyramid. Let’s go!
Then we see the pyramids in competitive condition. Their faces, edges and vertices are highlighted and scores are written on the board.
NARRATOR: Faces? Five. Edges? Huit. Et summits? Five more. Well tried the pyramid, the dice still have the upper hand.
The crowd applauds and the pyramids greet each other. Now we see the spheres in a position to face each other, and their faces, edges, and vertices are recorded. A negative buzzer sounds when 0 is dialed.
NARRATOR: Well, what about the sphere? So, faces? Well, that one. Edges? Zero summits? None. Oh my God! Too bad.
The spheres are there and we are angry.
NARRATOR: Oh come on, don’t be like that! Where are you going?
The sphere kicks the marker and his foot hurts. Salta.
NARRATOR: What a bad loser!
The scoreboard collapses, the rival sphere leaves and the curtain closes.
Ends.
3D shapes have faces (sides), edges, and vertices (corners).
A face is a flat or curved surface in a three-dimensional shape. For example, a die has six faces, a cylinder has three, and a sphere has one.
An edge is the meeting of two faces. For example, a die has 12 edges, a cylinder has two, and a sphere has none.
A vertex is where the edges meet. The plural is vertices. For example, a die has 8 vertices, a cone has one, and a sphere has none.
