Curated OER
Matrices: A Secret Weapon
Students perform operations with matrices. In this algebra lesson, students use cryptography and cryptanalysis to solve problems. They add, subtract, and multiply matrices.
Curated OER
Cryptography Implementation
Students explore cryptology. They write a research paper on cryptography. Using linear equations, students invent a code and write a secret message. Students complete cryptography puzzles.
Curated OER
Code Crackers
Students explore cryptology by studyingng about two simple coding methods, the Caesar cipher and the Vigenere cipher. Students then use matrices and their inverses to create more sophisticated codes.
