Back to School Math Mystery 6th Grade: The Case of the Awful August is a no-prep back to school math review for 6th Grade students. Get your students engaged right out of the gate with a high-stakes back-to-school investigation! The Case of the Awful August is an exciting 6th Grade August math mystery in which students solve clues to eliminate incorrect potions and discover the exact recipe to defeat the joy-stealing Grumble Gremlin. Because we know August is a unique time of year, this packet intentionally bridges heavy-hitting end-of-elementary review skills to ensure foundational mastery before diving into complex 6th Grade concepts. It is the perfect engaging math center, low-stress beginning-of-the-year assessment, or whole-class review.

The Story: The Case of the Awful August

The joy-stealing Grumble Gremlin is turning the city of Mathhattan dull and dreary with his Boring Bubbles! Students become lead detectives on a mission to track down the correct antidote – the “True Cure.” They solve clues to eliminate incorrect potions and discover the exact recipe to defeat the Grumble Gremlin, restore joy to the city, and make August AMAZING.

Set the scene with the optional video hook for the Case of the Awful August on your whiteboard or screen, then wrap up the case with the ending video. Students solve the math worksheets to unlock clues and eliminate possibilities after each clue to crack the case.

Math Skills Required to Unlock Clues

There are five clues to crack to solve the mystery:

  • Clue 1: Adding & Subtracting Decimals (Reviewing decimal alignment up to the thousandths place, including subtracting from whole numbers and using placeholder zeros)
  • Clue 2: Long Division (Dividing 3- and 4-digit dividends by 2-digit divisors with zero remainders)
  • Clue 3: Comparing Fractions (Comparing proper fractions with unlike denominators, reinforcing the ability to find common denominators)
  • Clue 4: Order of Operations (Evaluating expressions using parentheses, multiplication, division, addition, and subtraction – no exponents)
  • Clue 5: Volume Word Problems (Calculating the volume of rectangular prisms in real-world contexts using the standard volume formula)

Students must use critical thinking skills to work out what each clue is telling them to eliminate from the list of possibilities.

What is Included in this Math Mystery?

  • Optional animated video hook (with voiceovers) to set the stage (watch it here).
  • Ending video (with voiceovers) to wrap up the case.
  • Printable PDF case file: the mystery story, “Possible Antidotes” list, and five clue worksheets.
  • Google Slides digital version: 100% paperless. Assign it in Google Classroom. (Students must be in edit mode to type.)
  • Lead Detective Awards: printable certificates to celebrate your students’ success after finishing their math worksheets.
  • Complete answer key.

Easy prep: Print the student pages, staple or place them in a folder, and your students are ready to start. Or assign the digital version for a paperless option.

6th Grade August Math Mystery: Who It Is For

This edition is written for 6th Grade students and works in August and the first weeks of school, as a low-stress beginning-of-the-year review. Use it for:

  • August Math Centers
  • Beginning of the Year Assessments
  • Building Math Confidence
  • Back to School / Spiral Review
  • Sub Tubs (Easy Prep!)

Pacing and Timing: Time to complete will vary anywhere between 30 minutes and 2 hours or more. It mainly depends on how familiar your students are with the math mystery format, and how difficult they find the math skills covered in the clues. Please check the skills above to help determine suitability for your class.

I recommend pacing this activity by giving students one clue at a time. Once the whole class has completed a clue, move on to the next clue, either within the same lesson or in the next math session. New math content presented? Make a lesson out of it by modeling the math before diving into the clue. I like to say, “We must learn something new before attempting the next clue.”

How This August Math Mystery Works

Students read the mystery story (or watch the animated video hook) to set the scene. They must complete five math worksheets to unlock clues. Each clue helps them eliminate antidotes from their list until only the correct recipe remains! The final answer will help them defeat the Grumble Gremlin, restore joy to the city, and make August AMAZING. To celebrate, watch how the story ends with the included ending video!

Bonus: I snuck a little SEL into this pack! The winning antidote promotes a wonderful message about building a positive, grumble-free classroom community – perfect for a back-to-school discussion!

Effortless Assessment: The “Crack the Code” format allows you to verify student progress at a glance. If the code is correct, the math is correct!

Easy Grade-Level Differentiation

The Case of the Awful August is available in 6 grade editions. The story is the same; the math is different, so you can match each group to its level:

The 2nd-6th Grade editions can “clue swap” between editions to differentiate within one class. Grade 1 Math Mysteries are formatted for early learners and cannot be clue-swapped with the other grade versions. Read more: How to differentiate using Math Mysteries.
