Some years ago, David, an elementary School teacher wrote me asking if I can help them **designing a 2×2 Rubik’s cube for children**.

They want a **mathematical project for kids based on Rubik cube**. Fastly I answered with some links to learn to build 2×2 and 3×3 Rubik’s cube with dices and magnets. The are really cool hacks. But David needs something easier and cheaper. They came with simple premises.

- and it has to be cheap, very cheap

although everything must be said they just wanted a minimally manipulable cube.
