Describing 3D shapes

Describing 3D shapes Video of lesson

In this lesson, we will look closely at the properties of 3D shapes and talk about them, using new language to describe them.

You will need a tin, a cereal box and other shapes from around your house.

 

We will be using the words vertices, straight, curved, face and edge. Curved faces are known as curved surfaces. On a cone the vertex has a special name and it is an apex.

Repeat the sentence eg A cube has 6 flat faces.

 

Look at the shapes of objects in your home. What shapes are they? Can you describe them. If you are green standard compare objects saying what is the same and what is different about them.
