Inside the case file

Dive into shark facts through a case worth solving. This printable Shark Facts Reading Mystery turns a nonfiction passage on shark anatomy, senses, habitats, and conservation into a reading-detective investigation for Grades 3–6 classroom teachers, homeschoolers, and tutors. It drops straight into a Shark Week, ocean unit, or nonfiction reading lesson and turns comprehension practice into a case they want to crack.

Every comprehension answer clears another suspect, so students have to read closely and reason carefully to name the culprit — print it and go.

The Case

A book all about sharks has gone missing from the library, and no one knows who took it. Your students must read closely to learn the shark facts that point to the culprit — using every comprehension answer as a clue to rule a suspect out, until the missing book can be returned.

Students play Reading Detectives, reading about sharks and narrowing the suspect list one text-based answer at a time until the case cracks.
