A completely free 59-question resource — students toggle real binary switches to match a target value, watching binary, denary and hex update live, plus quizzes on units, conversions and binary arithmetic.
Full description:
Binary and hexadecimal conversion is usually taught with pen-and-paper place-value tables, so students rarely see cause and effect in real time. Bit Board fixes that: an interactive board of 8 physical binary switches lets students flip individual bits and watch the binary, denary and hexadecimal readouts update instantly, building genuine number sense instead of memorised steps. It is offered completely free, making it an ideal way for schools to trial the quality of these resources before exploring the rest of the collection.
• 59 auto-marked questions and interactive rounds across 6 colour-coded worlds, each with its own icon and visual theme
• A genuine interactive binary board: students physically flip 8 bit switches and see binary, denary and hex values update live across 15 target-matching rounds
• Covers the full OCR spec 1.2 syllabus: units of data (bit, nibble, byte, KB, MB, GB, TB), denary-binary conversion, hexadecimal, and binary arithmetic (addition, overflow, shifts)
• Career progression through six ranks (Bit Novice to Byte Master), XP, coins, streaks and unlockable badges
• A Field Manual (glossary) of every key term, linked directly to the OCR specification
• Every question includes a full worked explanation, not just a correct answer
• Completely free — no cost, no login, no install — runs as a single HTML file on any school device
Use it as the primary teaching resource for the Component 1 binary/hex unit, as a self-marking homework set, or as a free taster before browsing the rest of the shop; because there’s no cost barrier, it’s also ideal to share directly with students for independent revision at home.
