Codes and Ciphers

Help your students write and crack codes about my (fictional) cat, Muffins!

Part 1: Shift Cipher (Codes Part 1)

Let's encode and decode secret messages like Julius Caesar!

Part 2: Pig Pen Cipher (Codes Part 2)

Let's encode some secret messages with a cipher that was actually used during the American Civil War!

Part 3: Zig Zag Cipher (Codes Part 3)

Let's try a cipher that doesn't substitute new letters or shapes. We just mix things up.

Part 4: Path Cipher (Codes Part 4)

Now let's try the Path Cipher - a cipher that mixes things up even more than Zig Zag did.
