What are the properties of 3D shapes?

A curtain opens on a stage to reveal different shaped animated characters - a sphere, a cube and a pyramid.

NARRATOR: It's crunch time for the 3D crew. And who's going to take home the coveted, and totally pointless, prize of, eh… most properties?

Two cubes high-five as they prepare to compete.

NARRATOR: Well, anyway… A 3D cube has six square faces.

The faces of the cube are lit up to highlight all six. A judge writes 6 under faces on a scoreboard. Now the edges of the cube are highlighted. Then the judge writes 12 under edges, and the corners of the cube are highlighted next and 8 recorded under vertices.

NARRATOR: Edges – that's twelve. Right, what about corners, or vertices – that's the bits where the edges meet? Eight!

The cubes high-five each other as the crowd applauds.

NARRATOR: Oh, cube's really smashing this! Time for the mighty, square-based pyramid. Let's go!

Next we see the pyramids ready to compete. Their faces, edges and vertices are all highlighted and the scores written on the board.

NARRATOR: Faces? Five. Edges? Eight. And vertices? Five again. Good try pyramid, but cube's still in the lead.

The crowd applaud and the pyramids high-five each other. Now we see the spheres ready to compete, and their faces, edges and vertices are recorded. A negative buzzer goes when zero is scored.

NARRATOR: Finally, what about the sphere? So, faces? Well, just the one. Edges? Zero. Vertices? None. Oh dear! Oh well.

The spheres are disappointed and one is angry.

NARRATOR: Oh come on, don't be like that! Where you going?

The sphere kicks the score board and hurts his foot. He hops away.

NARRATOR: What a sore loser!

The scoreboard falls down, the competing sphere walks off disappointed, and the curtains close.

Ends.
