A Christmas computing quiz for KS3 and KS4: a PowerPoint with 32 questions in 4 rounds, answers revealed on click, a team answer sheet and answer key.

This is a festive end-of-term quiz built around the Computer Science curriculum. Pupils practise binary, hexadecimal and ASCII, recall key computing history and recognise famous computers and computer scientists, all while competing in teams.

What’s in each round

• Round 1, Festive tech: hardware, storage, file types, phishing and the web.
• Round 2, Binary baubles: decode binary and hexadecimal numbers and ASCII words written on baubles.
• Round 3, True or false?: computing history, from Ada Lovelace to the first text message.
• Round 4, Picture round: real photos of famous computers and computer scientists.

How to use it in class

Run it in tutor time or the last lesson of term; it takes about 40 minutes. Put pupils in teams of 3 or 4 with one printed answer sheet each. Each question has its own slide, and one click reveals the answer with a short explanation. If you’d rather mark at the end of a round, move on without clicking: the round answers slide reveals one answer per click while teams swap and mark. Teams can play a joker to double one round. A scoreboard you can type into and two tie-break questions finish the quiz.

Included

• PowerPoint (47 slides, 16:9) with click animations and an optional sleigh-bell sound on the title slide
• Printable team answer sheet (PDF, A4)
• Teacher answer key with explanations (PDF)
