Designed for 2nd, 3rd, and 4th grade students, this mystery math game combines problem-solving, logic, and seasonal fun.

The Mystery: Who Stole the Fall Colors?
Strange things are happening at school—leaves are changing colors too fast and falling off the trees. Someone has been stealing all the color! As a math detective, your students must follow the clues, solve the puzzles, and crack the case by narrowing down suspects.

What’s Included:

  • Subtraction from 100 (2-digit numbers)
  • 3-digit addition with regrouping
  • 3-digit addition and subtraction
  • Multi-digit addition
  • Word problems with addition and subtraction
  • Answer keys
  • Color and black-and-white versions for printing

Suggested Uses:

What Is a CSI Math Mystery?

CSI Math Mysteries are a printable escape-room–style activity where students solve puzzles, complete math problems, and eliminate suspects to crack the case. Instead of using physical locks, students work through a detective story using their math skills to uncover the culprit. They’re a classroom favorite for both teachers and students!
