Banks are responsible for keeping our financial information safe. Mathematics is what allows them to do just that! Pupils learn the math behind the cryptography that banks rely on. Using polynomial identities, learners reproduce the...

Use paint to teach about cryptography. Scholars explore public key cryptography by attempting to mix a secret color using paint. After the activity, they investigate the Diffie-Hellman method using prime numbers, exponents, and modular...

Students secure information online using cryptography. In this algebra lesson, students use RSA technology to encrypt information on the internet. They use modular reduction of natural numbers to understand prime number theory.
