Are you looking for a fun 4th, 5th, and 6th grade CSI Mystery Detective to engage your students in multiplication math practice, basic facts, and word problems? Then this printable CSI Mystery Detective is for you!

Capture your students' attention with this no-prep mystery by taking them on a journey to solve multiplication puzzles and clues. Students narrow down the possible suspects by completing each math task and marking them off until only one remains. Can your class crack the case?

This printable CSI Mystery Detective is perfect for Halloween, but it also works well at the start of the school year, end-of-year review, or as a seasonal spiral activity. It's also a great fit for homeschool math enrichment and independent learning.

What's included:

  • 2x1 digit multiplication
  • Multiplication maze
  • Multiplication match-up
  • Multiplication basic facts
  • Multiplication word problems
  • Answer key included

CSI Mystery Detective packs are independent escape room or crack-the-code types of fun math activities in which students identify suspects using puzzles and word problems instead of locks. This no-prep multiplication review is ideal for reinforcing fact fluency, solving real-world word problems, and bringing seasonal fun to your classroom.

Use it for independent work, partner tasks, early finishers, sub plans, math centers, or a fun alternative assessment during the Halloween season.
