Christmas Reverse Percentages Murder Mystery | Functional Skills L1–L2 & GCSE Foundation Maths

Bring festive fun into your maths lessons with this Christmas Reverse Percentages Murder Mystery, perfect for Functional Skills Maths Level 1–2, KS3, and GCSE Foundation. Learners use reverse percentage calculations to solve clues and work out who stole Santa’s sleigh, where it happened, and on which day. Only accurate original-value calculations will reveal the correct suspect, location and time, making this an engaging way to revise percentage increase and percentage decrease.

Students work through three sections: identifying the one suspect who is telling the truth, finding the location where exactly two calculations are correct, and narrowing down the day using original-value checks. Each clue requires learners to divide by decimal multipliers, interpret profit and loss, and evaluate whether statements are mathematically correct. This builds confidence in reverse percentage methods and supports accuracy, reasoning, and problem-solving.

The activity works well as a whole-class challenge, small-group task, revision activity or end-of-term lesson and includes clear, worked answers for teacher use or learner self-checking.
