Description

4th Grade Easter Math Mystery Activity to keep your students engaged and learning around the holiday! The 'Case of the Rotten Eggs' (4th Grade Edition) will add an exciting twist to your math sessions. Easy prep! Just Print & Solve! Or go paperless with the Google Docs option provided.


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

BONUS: Ending video added to wrap up the case!

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. 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 to discover WHERE Slimewort is hiding!


Math Skills Required to Unlock Clues

There are five clues to crack to solve the mystery:

  • Clue 1 Worksheet: What is the value of the underlined digit? (5-6 Digit Numbers)
  • Clue 2 Worksheet: Multiply numbers ending in zeroes (1-3 Digit Numbers)
  • Clue 3 Worksheet: Converting Improper Fractions to Mixed Number Fractions
  • Clue 4 Worksheet: Making Change (From $20)
  • Clue 5 Worksheet: Convert Place Values ( from ones to ten thousands) e.g. 200 tens = _______ Thousands

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

>The 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:

My students love it when I whip one of these "escape room" type projects out for holidays instead of regular old book math! I find these to be multi-age and skill appropriate for my classroom of 3-7th graders. The older students can help the younger ones as needed, but overall they can all do it on their own. It's a fresh alternative for holidays.

Mrs. J's creations is easily my favorite creator on TPT. I have so many of these resources and I use them every year. The kids love the challenges and gamification of it all and I love watching them work together to solve the mysterys. Thank you Mrs. J!

Questions & Answers

Standards

to see state-specific standards (only available in the US).
Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division.
Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
Multiply or divide to solve word problems involving multiplicative comparison, e.g., by using drawings and equations with a symbol for the unknown number to represent the problem, distinguishing multiplicative comparison from additive comparison.
