Algorithms & Programs: Worksheet

A three-page unplugged worksheet that introduces the heart of KS1 computing — algorithms and programs — without needing a screen. Page 1 builds the concept of an algorithm by asking children to write step-by-step instructions for an everyday task (making toast). Page 2 introduces debugging — finding and fixing the bug in a set of broken instructions. Page 3 has children program a robot to navigate a grid using arrow commands. These three pages map directly to NC requirements 1 (algorithms), 2 (debugging), and 3 (predicting behaviour). Answer key included with notes on multiple valid solutions — programming nearly always has more than one right answer.
