Description

Preparation
– 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: Multiplying Numbers Ending in Zeroes
Clue 2: Reading Decimals Expressed in Words (tenths, hundredths and thousandths)
Clue 3: Multiplying 2-Digit and 3-Digit Whole Numbers by 1-Digit Whole Numbers
Clue 4: Equivalent Fractions
Clue 5: Adding and Subtracting Fractions with LIKE Denominators only (simplifying answers required).
Students must use critical thinking skills to figure out what the clue is telling them to eliminate from the list of possibilities.

Videos
There’s an optional video hook that you can use to set the stage to engage!

Plus an ending video to see what happens after the case is solved!

Printable awards are included to celebrate students’ success! 

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?
The time to complete this math activity will vary anywhere between 30 minutes and 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.
