With this Lego Digital Designer model, you can see and touch the numbers. Every positive integer is vertically represented. Zero is just a sequence of grey tiles while the number one (first Lego on your left) corresponds to a single lilac 2 x 2 brick. As a result, it is possible to play a game where each person tries to guess the secret number of someone else. Children from any country could learn that math is a universal language independent of sounds and symbols.
