Dividing fractions worksheets and dividing-whole-numbers-by-unit-fractions activities for 5th grade and 6th grade are all included in this zombie Mini Mystery Detective pack of math worksheets. Students divide a whole number by a unit fraction to solve five spooky detective cases — every problem works out to a whole-number answer, so the focus stays on the skill. Perfect for math centers, morning work, early finishers, and spiral review. Completely no prep — just print and go.

What's Inside

• Dividing a whole number by a unit fraction — for example 6 ÷ 1/4 and 3 ÷ 1/10 (the 'how many fourths are in 6?' idea)
• Building fraction-division fluency with unit fractions from halves all the way to twelfths
• Every problem lands on a whole-number answer, keeping students focused on what it means to divide by a fraction
• Self-checking answer keys for every case

Five zombie mysteries to solve: The Gnawed Bones, The Torn Shroud, The Oozing Trail, The Cracked Tomb, and The Feral Feast. Answer keys included for every case.

What is a Mini Mystery Detective?

A no-prep detective activity where students solve math problems to cross off suspects and unmask the culprit — like an escape room without the locks. Every correct answer eliminates a zombie suspect, so the activity is self-checking: solve the math correctly and only the villain is left standing. Skill practice plus critical thinking in one engaging worksheet set.
