Description

If rounding practice in your classroom usually means another worksheet students rush through—or tune out completely, you’re not alone. Rounding can feel abstract, and traditional practice doesn’t always keep students engaged long enough for it to stick.

This rounding detective math mystery helps you move from low engagement and surface-level practice to focused, curious students who want to solve every problem.

Instead of worksheets, students solve rounding word problems using a self-checking Google Sheets math mystery game. Each correct answer unlocks a clue, eliminates suspects, and brings them closer to solving a school mystery—while built-in feedback keeps them on track the entire time.

It’s math practice with a purpose—and a story students can’t wait to finish.
