This version requires regrouping skills; the numbers in the questions are within 100

>> Also included:

- Editable Mystery List and two premade alternative lists to swap out for a different mystery solution
- Answer Key
>> Great activity for:
- consolidation
- extra practice/review
- enrichment
- homework packs or assignments
- early finishers.
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, 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."
-----------------------------------------------------------------------------------------------
How long will this activity take?
The time to complete will vary anywhere between 30mins - 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.
