STEM Behind Hollywood - “Cipher Solvers”: Math and the Cryptic Missive

There is a buried treasure located somewhere on the family’s property. A pair of geometry students find a cryptic message that launches them on the treasure hunt using algebra, geometry and cryptology.

During this webinar, presenters introduce a new STEM Behind Hollywood math activity and show how the students use TI-Nspire™ CX and TI-84 Plus CE technology to:

• Decipher the code
• Plot ordered pairs and write equations of lines
• Employ dynamic geometry and an interactive program to construct the circumcenter of the triangle created by the three lines
