Distance Learning Update: There's a Word Document within the folder that contains a Google Doc link to share this resource with your students via Google Classroom or Drive. Parts of the pages are editable so that your students can complete without having to print the pages. Please note, you will need to make a copy of the Google Slides to your drive before you can edit.
--> Plus a PowerPoint that contains the Worksheets as images with editable textboxes for those who use Microsoft.


Useful for a fun spiral math review session!


Students must use their math skills to unlock clues. Then, use their powers of deduction to narrow down the list of suspects to find the Valentine Villain and rescue the kidnapped pets!
Suggestion: Pace the clues one by one to keep the class at the same point. If using the clues in a different order, keep the suspect list away from students until all five clues are completed and discovered.
---------------------------------------------------------------------------------------------
Optional VIDEO HOOK available to use to introduce students to this math mystery activity. Check out the preview section to view the video.
------------------------------------------------------------------------
Preparation
- Print the student pages, staple or place in a folder, and your students are set to go.
- Have the video hook ready for viewing at the start of the lesson on an IWB, iPad or computer monitor screen.
- Digital: Make a copy for each student when assigning via Google Classroom or if using the PowerPoint, send it to your students as is for them to complete.
-----------------------------------------------------------------------------------------------
Math Skills Required to Unlock Clues


There are five clues to crack to solve the mystery:


Clue 1: Adding Three Addends (Single Digits only)
Clue 2: Comparing Numbers between 1-99
Clue 3: Greater than or less than 50
Clue 4: Subtract a single digit (1-5) from a double-digit number (no regrouping) - Vertical algorithm format
Clue 5: Subtract ten from double-digit numbers - Vertical algorithm format


Students must use critical thinking skills to figure out what the clue is telling them to eliminate from the list of possibilities. This is a great opportunity for a class/group discussion if there is ever a dispute in the deductive reasoning process.
----------------------------------------------------------------------------------------------
Multiple Uses
- 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 will vary anywhere between 30mins - 2 hours or more! It mainly depends on how familiar your students are with the math mystery 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.
​

This Math Mystery is also available in a CSI Digital Mystery Game format that can be played on any device with an Internet Connection. The GAME option contains more graphics and is not the same style as the digital worksheets provided in the printable packets > CLICK HERE to learn more about this option.
