The Case
A piece of Labor Day history has gone missing, and a line-up of suspects is waiting. The only way to crack the case is to read closely about Labor Day — why it began, the workers and unions behind it, and how it is celebrated today — using every comprehension answer as a clue to rule a suspect out, until just one remains.

Students take on the Reading Detective role, reading about Labor Day and using every text-based answer to eliminate a suspect until one remains.
