Case Summary

You've bought your Mom the perfect box of chocolates for Mother's Day and wrapped them up just right — but your older brother has decided to be a pain and hidden them. The good news: he hasn't eaten them. The catch: he's left behind a set of clues, and the only way to find the chocolates is to solve every one.

Working clue by clue, students solve a multiplication maze, crack a division puzzle with a secret code, plot points on a map using coordinates, and tackle problem-solving puzzles — each one pointing closer to the hiding spot.

The math does the detective work: students can only follow the trail if their calculations are spot on, so accuracy matters from the very first page. It's seasonal practice that feels like a game, not a worksheet.

Can your class crack your brother's clues and find Mom's chocolates before the big day? Hand them the case file and find out.

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.
