Eighth graders put their design skills to the test with the Project Lead the Way Puzzle Cube Challenge.
The problem tasked students with designing a three dimensional puzzle system that met specific criteria, such as using only 3/4-inch cubes to create interlocking pieces of varying shapes. The design criteria were:
- The puzzle must be fabricated from 27 – ¾” plastic cubes.
- The puzzle system must contain exactly five puzzle pieces.
- The five puzzle pieces must assemble to form a 2 ¼” cube.
- Each individual puzzle piece must consist of at least four, but no more than six cubes that are permanently attached to each other.
- No two puzzle pieces can be the same.
- Some puzzle parts should interlock.
The students used an app called GeoGebra to help them create 3D renderings of the puzzle pieces and experiment with different designs.
