| Description: For anyone else teaching Middle School, this is a great link for linking Prime Numbers and Cryptography. I then usually play a simple (but very fun!) game: > Show a 1-100 grid with prime numbers highlighted > I (secretly) multiply two prime numbers, and tell the result > Students have to figure out (using a calculator) which numbers I multiplied > They then try this on each other It really gets them using the prime numbers, and introduces the idea of the "lock" (easy to lock, very hard to open).
