Project due 10/7
Pre-Algebra Project:
People and organizations use ciphers all the time to get information to other
people without unwanted people knowing. This has been going on since Julius
Caesar was alive.
There are many different ciphers that have been implemented and used over
time. For example, there is such a cipher called PigPen Cipher, ASCII code,
Stenography Cipher, Monoalphabetic and Polyalphabetic Ciphers; just to name a
few.
Option 1
Section 1:
Try to decipher the box using the ASCII code below. Can be found on the
website below.
Section 2:
Writing a Cipher
With the letters you wrote to a friend, write it using the Caesar Cipher. The
Caesar Cipher, used by Julius Caesar, substitutes one letter for another by
shifting each letter in the alphabet three places: A becomes D, B becomes E,
and so on. In Caesar Cipher, dog is written grj. Write a letter in Caesar
Cipher to someone. Be sure to include both the encoding and decoding of the
letter. You need at least 8 sentences.
(Pg. 33 in your textbook).
Section 3:
Writing a Code
Codes don't always use numbers or letters. In "The Adventure of the Dancing
Men," the detective Sherlock Holmes used deductive reasoning to decipher a
code that substituted stick figures for letters. Using the substitution
symbols of your choice, invent a cipher. Use it to write a message. Don't
forget to provide the key in the form of a table like that in Activities 1 & 2.
You can visit this website to read more on codes and their uses:

Option 2
Section 1:
Research and write a paragraph about Morse code. Be sure to include what it
is, when it was used, why it was used, and what it looks like. Create a chart
of Morse code. Try to write a paragraph using Morse code (Remember: a
paragraph is at least 8 sentences long). Be sure to write the encrypting and
decoding of it.
Section 2:
Create your own code. Your code can use number, letters, symbols, etc. Be
sure to create your own and not copy’s someone’s ideas. With this new code
that you created, make a game or puzzle out of it for someone else to solve.
Make the paper aesthetically pleasing.
Option 1 Time line:
ASCII code should be done by Tuesday, September 27, 2011.
Caesar Cipher Rough Draft (both copies) should be done by Friday, September
30, 2011.
Writing your own code should be done by Tuesday, October 5, 2011.
Final Copies and presentation board should be done by Friday, October 7, 2011.
Option 2 Time line:
Creating your own code should be done by Thursday, September 29, 2011.
Rough Draft of your code (both copies) should be done by Friday, September 30,
2011.
Morse code research should be done by Wednesday, October 6, 2011.
Final copies and presentation board should be done by Friday, October 7, 2011.
Rough Draft Due Date: Friday, September 30, 2011
**We will read each other’s letters in class to make sure that we are on the
right track and that our encoding and decoding is correct.**
Final Due Date: Friday, October 7, 2011
