This challenge can be used as a Pi Day activity on March 14th or can be used as a review of circles. Clues require knowledge of pi, understanding of circle vocabulary words, and use of the formulas for circumference of a circle, area of a circle, and volume of a cylinder. (A hint card is included if needed!)

The introduction for the Escape Challenge is based on characters from Sir Cumference and the Knights of the Round Table by Cynthia Neuschwander. Small groups of students compete against each other to complete the five tasks and unlock the six locks to escape the dungeon.

This challenge is designed to use either a Google Forms Lock to which a link is included OR index cards if you want a low-tech version.

This packet includes a link to the google lock, a link to an introduction video, and all handouts needed for the five tasks. Some assembly of materials is necessary for this to be a success, but it will be an unforgettable activity for students!

Also included are signs to use in the student's Victory Escape Photos!
