Kids use Scratch blocks wired to ImageNet and simple face, sound and text classifiers to build supervised models for chatbots, Pac‑Man agents, rock‑paper‑scissors, postcode OCR and a book‑shelf sorter; many projects run successfully but failures reveal lessons. Training more examples steadily improves the Pac‑Man controller, a crowdsourced tic‑tac‑toe model reaches draws with hundreds of samples, a newspaper headline project teaches train/test separation, and experiments with a confidence threshold (kids call it “shy”) expose calibration, bias and how stacked models combine.
