# Creating Cubes

## Creating Cubes

Arrange nine red cubes, nine blue cubes and nine yellow cubes into a large $3$ by $3$ cube.

No row or column of cubes can contain two cubes of the same colour.

### Why do this problem?

This activity is is very good as a spatial challenge. Some pupils who are not high-achieving in number work may excel in spatial work and this gives them that opportunity.

### Possible approach

You can lead up to this challenge by starting with a cube using two colours first. Having plenty of interlocking cubes available for children to try out their ideas will be essential.

### Key questions

How could you start the cube?
Is there only one way of doing it?
Have you all got the same solution?
Are some of the solutions similar?
