Originally written for Algebra 2 students as a fun end-of-year after-testing activity. It's a lighthearted take on the subject but includes some more serious math. This is a 58-page mini-textbook that covers some basic elements of classical cryptography, including Caesar, vigenere, affine, and keyword ciphers, among others. It discusses modular arithmetic, solving algebraic equations with modular arithmetic, and some basic work with prime numbers (coprimes, Ulam's spiral, Mersenne Primes). The

This is not a sufficient curriculum to for factoring in the sense that it is not nearly enough practice, but

With text taken from the website of Doug Hutchison, this activity combines biographies and history of the first Roman triumvirate. As an activity, students are broken up into groups of seven and each given one biography of a relevant historical figure. They are then tasked with filling in the blanks of a historical cloze-style activity, where each blank requires knowledge derived from the seven biographies distributed among students.
