**What are Mini-Math Mysteries?**

Mini-Math Mysteries are a fun 'game-like' one-page activity to practice math skills. They are a condensed version of a mystery and follow a simple elimination structure where students will use their answers to eliminate possibilities. The mystery story is short (a couple of sentences to a paragraph), and unlike my regular mysteries, there are no clue messages or video hooks for these. I've designed these for educators who want something quick and short to assign to students while keeping it fun!
