Math Mystery Worksheet Generator (Solve the Clues, Find the Culprit)
Print a two-page math whodunit for ages 7–11. Read the case, meet six suspects, then solve each clue's problems: the answers tell you who to cross out, and the last suspect standing did it. Pick the case and the skill, three or four clue sets, and an answer key.
Every mystery has exactly one culprit: each clue crosses out at least one suspect and only one survives all of them. Page 1 holds the case, the suspects and clues 1–2; page 2 the rest and the culprit box. One page fits the whole mystery on a single sheet.
