Distance Learning Update: I've added a Word Document in the folder containing a Google Slides link to share this resource with your students via Google Classroom or Drive. Parts of the pages are editable, so your students can complete them without printing the pages. Please note you will need to make a copy of the Google Slides to your drive before you can edit.

MATH SKILLS

There are five clues to crack to solve the mystery:

  • Clue 1: Find the Missing Angle in Triangles
  • Clue 2: Find the Missing Angle in Transversals of Parallel Lines
  • Clue 3: Pythagorean Theorem - Find the Missing Side/Hypotenuse
  • Clue 4: Volume of Spheres
  • Clue 5: Circumference and Area of Circles

(US Customary and Metric options provided)

Also included:

  • Printable awards
  • Answer Key
  • Editable locations list

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 and how difficult they find the math skills covered in this particular mystery. Please check the math skills outlined in the clues above to help determine suitability for your class. I highly 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." There are many ways to implement this activity in your classroom; learn more in the blog post link below: Read Blog Post: Five Easy Ways to use Math Mysteries in your Classroom.
