A low-prep Year 9 Christmas maths escape room: six A3 room posters, one answer sheet per team, a self-checking door code, certificates and maths colouring, including a Mission Control HTML timer page: reads the story aloud, 45-minute countdown, works offline
Your class is spending Christmas Eve at the famous Ice Hotel, but the heating has failed and every door has frozen solid! Teams of 3–4 move round six room posters pinned around the classroom, solving four questions in each to find one letter of a six-letter door code. The activity lasts 50–60 minutes, is festive without being religious, and covers Cambridge Lower Secondary Stage 9 and KS3 Year 9 maths.
The rooms:
• Room 1 – The Reception Desk: indices & standard form
• Room 2 – The Ice Bar: percentages & proportion
• Room 3 – The Frozen Lab: algebra
• Room 4 – The Snow Graph Gallery: graphs & sequences
• Room 5 – The Ice Sculpture Hall: geometry & measures
• Room 6 – The Northern Lights Deck: statistics & probability
Hands-free for the teacher: every poster has a snowflake answer bank, so teams check their own answers; a Decoder turns each room total into a letter and catches common mistakes; and an Exit Door check confirms the code. Hint cards are self-serve.
Limited printing: six A3 posters per class (they also print on A4) and one double-sided A4 answer sheet per team, with the Decoder on the back.
What’s included:
• Room posters (A3), plus optional briefing, Decoder and Golden Snowflake bonus posters
• Escape Log answer sheet with Decoder
• Mission Control HTML timer page: reads the story aloud, 45-minute countdown, works offline
• Fillable Certificate of Escape
• Two Christmas maths colouring sheets (colour by answer) with answers, for early finishers
• Hint cards and a three-page teacher guide with full answers and working
All maths is typeset with LaTeX and every answer has been checked. No calculators needed.
