Ratios and Proportions Activity Murder Mystery with Proportional Relationships


Looking for a low-prep, highly-engaging activity to practice setting up and solving for ratios and proportions from word problems and equations? This murder mystery is the perfect way for to practice working with proportional relationships!

Students become suspects after a carnival worker is murdered. There are only a few clues about the murderer, and the students must set up and solve proportions to figure out who it is!

Students are given character cards when they enter the room and assume the role of a carnival visitor. Their fun-filled day comes to an end when a carnival worker is found dead. They must work through the clue/worksheet to clear their own name and figure out who among them is the murderer!

The digital version allows students to work independently to solve the mystery by solving for clues on the clue sheet to eliminate suspects and figure out who the murderer is. This version is created in Google Slides & includes full student and teacher instructions!
