Multiplying Fractions (with Simplifying)

Inside the case file

Multiplying fractions with simplifying worksheets for 5th grade and 6th grade: five math cases, each a Mystery Detective page where students multiply and reduce to lowest terms. No prep, print and go, full answer keys, for math centers, warm ups, early finishers, homework, test prep and sub plans. Each answer strikes a name, a place or a time off the clue lists and an unsimplified answer matches no clue, so these fraction pages insist on the last step without you saying a word, which is what a CSI Mini Mystery Detective does that a plain fraction page cannot.

Simplifying is built into every answer here, because an unreduced fraction matches no suspect, so students finish the job every time without being reminded. One case fits a period, so five of them make a self-marking week of the fraction unit, and any one of them works alone as a sub plan. It is math practice in a Mystery Detective format.

Every answer has to be in simplest form before it will match a clue. That gives students a reason to finish the last step instead of stopping at the product. The cases include a class prize, money found on the ground and a teacher who's been kidnapped.

The Cases

1. Class Prize - who wins the class prize
2. Lost Money - finding the owner of some money
3. Box of Chocolates - chocolates left on the desk
4. Kidnapped - a teacher taken from school
5. Acts of Kindness - random good deeds

What's Inside

• Five color case pages of fraction multiplication
• Black and white copies of all five
• An answer key for every case
• Every answer simplified to lowest terms
• Teacher instructions

What Is a CSI Mini Mystery Detective?

Each case has a short story, the problems and clue lists, all on one page. Every clue has a value. Students cross off a clue when an answer matches it. The clues left at the end are the solution.

When to Use This Resource

Use this once multiplying fractions has been taught and students are working on their own. It's useful before a test, and as a refresher for 6th graders before mixed numbers. The cases can go home as homework, to a small group, into a sub folder or into a homeschool week.

Grade Levels

Written for 5th grade and 6th grade.
