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

Math Skills Required to Unlock Clues

There are five clues to crack to solve the mystery:

- Clue 1: Mentally add ten to numbers less than 100
- Clue 2: Place Value Models up to 50 only
- Clue 3: Missing numbers on a Hundred Chart
- Clue 4: Comparing Numbers up to 100
- Clue 5: Mentally subtract numbers from numbers 100 or less

Students must use critical thinking skills to figure out what the clue is telling them to eliminate from the list of possibilities. Ensure students read and comprehend clues carefully!

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

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.
