Ratio Murder Mystery | KS3 GCSE Functional Skills Maths Activity & Worksheet

Transform ratio revision into an exciting detective challenge with this Ratio Murder Mystery, perfect for engaging learners in KS3, GCSE Foundation Maths, and Functional Skills Maths L1–L2. Instead of routine ratio questions, students work through a full mystery story, solving five ratio-based tasks to uncover the victim, location, murderer, time of the crime, and the motive. This makes ratio practice far more memorable, meaningful, and fun for all abilities.

This unique activity blends core ratio skills with problem-solving and logical reasoning. Students must simplify ratios, divide in ratios, work with maps and scales, apply multi-step ratio problems, use proportion and speed/distance/time links, and combine ratio information to unlock clues. Every section leads them closer to solving the crime, keeping them fully engaged from start to finish.
