*I can recognize and describe solid figures.

.

*I can describe cubes and rectangular prisms.

Plane (2D) vs Solid (3D)

Plane shapes are FLAT.

.

.

Solid figures have thickness and depth. They are NOT flat.

​

3D vs 2D

A cube has 6 equal faces. On this cube, only 3 faces are VISIBLE.

The other faces cannot be seen. But they are there!

Cube Faces

Each face is a SQUARE with 4 RIGHT angles and 4 EQUAL Edges.

Cube Faces

A cube has 8 vertices. 4 on top and 4 on the bottom.

Cube Vertices

How many vertices are VISIBLE on this cube? How many vertices are hidden?

Draw

Circle the cubes. Put an X on the shapes that are NOT cubes.
