Students build and draw three-dimensional cubes made up of small unit cubes. Student study patterns by analyzing the number of sides painted of each unit cube, which made up the larger painted cube.

## Materials

- Grid or isometric dot pater
- Centimeter cubes or similar (sugar cubes are great for this activity!)

## Task Instructions

Imagine that we paint a 4 x 4 x 4 cube blue on every side. How many of the small cubes have 3 blue faces?

How many have 2 blue faces?

How many have 1 blue face?

How many have not been painted at all? How many faces would be painted in a cube of any size? Think visually!
