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.
- Children of 10 years must be able to build it, so we forget about elaborate and dangerous tools and processes
- and it has to be cheap, very cheap
although everything must be said they just wanted a minimally manipulable cube.
