Case Summary

A secret base has been discovered on the moon. Nobody knows how it got there, whose base it is, or what secrets are hidden inside — and every astronaut sent before has vanished without a trace.

Now your students take command as the new Moon Mission Leader. Their job: work through the base's hidden passageways and deadly traps by solving math clues, ruling out one room at a time.

With every solved clue, the list of rooms shrinks until only one is left — the hideout of the secret base leader.

Can your investigators crack the clues and locate the leader of the moon base? Sharpen those pencils and start the mission.

How CSI Math Mysteries Work

CSI Math Mysteries turn regular math practice into a clue-based investigation. Students solve problems, use their answers as evidence, and eliminate suspects until the case is solved.

1

Read the Case

Students begin with a short mystery scenario and find out what needs to be solved.

2

Solve the Clues

Each clue gives students focused math practice using the target skill for that resource.

3

Eliminate Suspects

Students use their answers to remove suspects from the investigation one clue at a time.

4

Crack the Case

By the end, only one suspect remains and students can reveal the answer to the mystery.

No apps, locks, passwords, or student logins are required. Just print and go.
