LO – TO UNDERSTAND THE PROPERTIES OF 3D SHAPES

LETS RECAP FROM YESTERDAY.

HOW CAN WE DESCRIBE THESE SHAPES?

WE CAN USE WORDS LIKE…

FACES

EDGES

VERTICES

FACES OR SIDES

All 3D shapes have faces.

EDGES

All 3D shapes have edges apart from a sphere.

CORNERS OR VERTICES

All 3D shapes have vertices apart from a sphere.

WE CAN ALSO SAY WHAT SHAPE THE FACE IS.

The face is the shape of a square.

USING THESE WORDS, HOW COULD WE DESCRIBE A CUBE?

It has…•6 faces that are square shaped•12 edges•8 vertices

I AM A PRISM

I AM A PYRAMID

I have one base (also called a face).

All my other faces slope and meet at one point.

I am a Non-Prism
