Math @ IMSA: Monday

What is the difference between a cipher and a code? Ask your students! Today, students were engaged in an exciting activity where they decrypted messages using various transposition and substitution ciphers. Ask your student about their findings!  In small groups throughout the day students used their new knowledge of ciphers to encrypt messages and design keys to their messages. While sharing in small groups students discussed the historical background of ciphers and worked on a team to manipulate four different types of ciphers. Student will continue to examine and manipulate these ciphers all week in small groups and independently.

Ask your student:

Summarize some of the properties which we learned about within a cypher?

Describe the procedure to quickly and easily decode a monoalphabetic substitution cipher?
