# Cipher Solvers

Activity Overview

In this code breaking activity, students are challenged to identify patterns, unravel clues, and triangulate a point on a treasure map.

Objectives

• Students will discover how to encrypt and decrypt a message.
• Students will learn what a Caesar cipher is and use it to solve a
riddle.
• Students will find equations of lines given two points on the line.
• Students will solve systems of linear equations to find vertices of
triangles.
• Students will find equations of lines that are perpendicular
bisectors of given segments.

Cipher Solvers challenges your students to identify patterns, unravel clues and triangulate a point on a treasure map.

It’s an ideal opportunity for students to have fun solving problems while exploring, analyzing and understanding concepts like:

• Equations of lines through points
• Midpoints of segments
• Equations of perpendicular lines
• Intersections of lines
