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
