Description

The 'Case of the Rotten Eggs' (3rd Grade Edition) will add an exciting twist to your math sessions. It's easy to prep—just Print and solve! It's also now available with Google Slides as a paper-free option.


Optional video hook included for introducing the case! (Check it out in the preview section)

Update: >>The Videos now have voiceovers<<


Easy Prep!

  • PDF printable version - print and copy the worksheets, and your student detectives are ready to solve!
  • Google Slides Digital version - Find the link in the Teacher Instructions section to open the worksheets digitally in Google Slides. Please make a copy for your students and assign it. Students must be in 'edit' mode to enter answers.


Students must use their math skills to eliminate hideouts and discover WHERE Slimewort is hiding!


Math Skills Required to Unlock Clues

There are five clues to crack to solve the mystery:

  • Clue 1: What is the value of the underlined digit? (3-Digit Numbers)
  • Clue 2: Multiplying by Multiples of 10
  • Clue 3: Match Fractions to Visual Models (No reducing to the lowest terms required).
  • Clue 4: Balancing Addition Equations (3-Digit Numbers)
  • Clue 5: Convert From Expanded Form ( 3 and 4-digit numbers)

Students must use critical thinking skills to determine what clues are telling them to eliminate from the list of possible hideouts.

>> Pack includes a mystery declaration sheet, answer sheets, an elimination guide, an editable suspect list, and printable awards.

----------------------------------------------------------------------------------------------

How long will this activity take?

The time to complete will vary anywhere between 30 minutes and 2 hours! It mainly depends on how familiar your students are with the math mystery format and how difficult they find math skills covered in the particular mystery. Please check the math skills outlined in the clues 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 within the same lesson or 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." There are lots of ways to implement this activity in your classroom; learn more in the blog post link below:
