This is a Valentine's Day themed math mystery that is best for grades 4 & 5. The geometry topics focus on types of angles, (acute, right, obtuse or straight angle), types of lines (parallel, perpendicular or intersecting), symmetry, finding the measure of an unknown angle and classifying angles by side measure (equilateral, isosceles or scalene). This product aligns with the 4th grade Engage NY Module 4 or Eureka math. While this product product specifically aligns with grade 4 standards, it would be a great review for 5th grade students nearing state test time; it would be a fun, engaging review that could be done as a whole group or independently. As for 4th grade students, this product would be great for a whole group review, independent fast finisher work, review prior to the end of module test or center work.

Students will read the scenario in the beginning to find out what the problem is, read over the suspect list and solve five clues to narrow down the suspect to find the suspect that committed the crime. My students love it when they're allowed to mark their own guess prior to completing this!
