Groundhog Day Math Mystery: Case of the Kidnapped Groundhog - 2nd Grade Edition
Groundhog Day Math Mystery: the Case of the Kidnapped Groundhog This math activity is a fun way to review and practice mathematical skills in the classroom or at home. Ideal for spiral review, consolidation, math centers, homework, enrichment, early-finisher, or the sub-tub.
Easy prep! Just Print & Solve! Or go paperless with the new Google Slides option provided within your download.
⭐A video hook is provided to set the stage to engage! Check out the video hook in the preview section.
⭐A bonus ENDING VIDEO clip is included to celebrate finishing the mystery.
(Please note: The videos now come with voiceovers to read the story).
Students must complete math worksheets to unlock clues. Then, use their powers of deduction to narrow down the list of possibilities to solve the mystery case!
- Easy Prep! Print the student pages, staple or place in a folder, and your students are ready to start the math game of solving the mystery.
- Have the mystery video hook ready for viewing at the start of the lesson on an IWB, iPad or computer monitor screen.

Math Skills Required to Unlock Clues
There are five clues to crack to solve the mystery:
- Clue 1 Worksheet: Addition (within 20)
- Clue 2 Worksheet: Convert 3-digit numbers from expanded form
- Clue 3 Worksheet: Comparing Numbers (2-digit and 3-digit numbers)
- Clue 4 Worksheet: 2-Digit Subtraction (with some regrouping)
- Clue 5 Worksheet: Making 20 - Fill in the missing number to make the addition/subtraction sentence true
Students must use critical thinking skills to figure out what the clue is telling them to eliminate from the list of possibilities.
There's an optional video hook that you can use to set the stage to engage!
- Suitable for independent, pairs, or group work.
- Use as part of your math centers, add to your sub tubs, make it part of your early finisher tasks, give for homework, or make it part of your classroom practice/review sessions.
I recommend pacing this activity by giving students one clue at a time. Once the whole class has completed a clue, then move on to the next clue either 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."
-----------------------------------------------------------------------------------------------
How long will this activity take?
Time to complete this math activity will vary anywhere between 30mins - 2 hours or more! It mainly depends on how familiar your students are with the math mystery game format, as well as 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.
