Faces

3D shapes have faces. A face is a surface on the

shape that you can touch.

Flat Faces and Curved Faces

Faces on 3D shapes can be flat or they can be

curved.

Curved Faces

Put a 3D shape with curved faces on a table.

See what happens when you push it.

What happened?

Shapes with curved faces and curved edges can roll.

Building with 3D Shapes

We can use 3D shapes to build.

Are flat faces or curved faces better for
building with?

Building with 3D Shapes

Flat faces are easier to build with, because shapes

with curved faces will roll.
