KS3 Computing Bundle — Algorithms, Binary, Networks and an Escape Room

Three complete KS3 computing lessons and a revision escape room, all written to be taught by a non-specialist.

What’s in the bundle

1. Algorithms and Flowcharts — sequence, selection and iteration, the four flowchart symbols, a trace task with a loop, a write-your-own, and linear against binary search
2. Data Representation — binary both ways, binary addition with an overflow, hexadecimal, hex colour codes, ASCII, and image file sizes
3. Networks and the Internet — LAN and WAN, hardware, topologies, packets, IP and MAC addresses, DNS and protocols
4. Escape Room: The Server Room — four locks revising all of the above, print and go, no props

Every lesson ships as a print-ready PDF and a fully editable PowerPoint, with teacher notes that set out the subject knowledge rather than assuming it, the misconceptions to watch for, worked answers to every task, and a scaffolded support version. Dyslexia-aware design throughout, following British Dyslexia Association style guidance.

Every conversion, trace and calculation was generated by computer and checked back against the printed answer key.
