Dutch primary schools are using Montessori pegboards to introduce children to coding work. The colours and numbers of the code reveal a pattern. Pupils must work the code, line by line, to build the surprise picture. Since not every classroom has pegboards, I’ve reworked the principle as a “paper-and-coloured-pencil” activity for individuals or pairs. P.S. I protested to my resident IT guru that it seemed a stretch to call this “coding” as it looked more like a knitting or weaving pattern to me. “Well,” he answered, "The punch cards of the Jacquard loom were direct ancestors of those in early computers”. I stand corrected!
