The Case

A tiny culprit is on the loose, and a line-up of suspects is waiting. The only way to crack the case is to read closely about insects — their body parts, life cycles, and role in the world around us — using every comprehension answer as a clue to rule a suspect out, until just one remains.

How the Reading Mystery Works

Students take on the role of Reading Detectives, reading about insects and bugs and eliminating a suspect with each correct, text-based answer until one is left standing. The passage holds every answer.
