You have been selected to be a part of a Secret Spy Team! As a mathematician in training, your expertise with functions will be helpful in securing top secret communications between your team members. Your team’s goals and objectives are to encode/decode secret messages with details on your next team meeting. Each member of the team will contribute with one detail for the team’s secret meeting and use functions to encode and decode the messages to make them unreadable to anyone outside of your team.
Each letter of the alphabet and a blank space can be represented as a two-digit number.
Numerical Look-Up Table:
A = 1
B = 2

Your instructor will post your team’s coding/decoding pair of functions in your discussion. You have already been placed in the assigned group for this discussion. You and your group are the only ones who will post here. You will use the coding function to encode your message and share with your team. Then other team members will decode the message with the decoding function.
Post 1: Initial Thread
You will need to encode two messages to your team.
Parts a and b are your work.
Part c is what you post!
a) First part of message: Using your first name and the Numerical Look-Up Table, represent the following message numerically.
T
H
I
S
I
S
F
I
R
S
T
N
A
M
E
Then, using your team’s coding function, encode the above initial message.
T
H
I
S
I
S
F
I
R
S
T
N
A
M
E
b) Second part of message: Pick one of the following details that has not yet been chosen to coordinate your team’s secret meeting. Write a short message to the team of four words or less. Encode the message using the numerical look-up table and coding function.
Location: Decide on a location to meet. For example, MEET AT STARBUCKS
Where to Be: Decide where to be at the location. For example, SIT BY THE DOOR
Time: Decide on the time to meet. For Example, MEET AT NOON
What to Bring: Decide on what to bring. For example, BRING THE MAP
What to Wear: Decide on what each team member should wear
What to Do: Decide on what to do at location. For example, BUY A COFFEE
Password to Say: Decide on password to say for meet up. For example, LIKE TEA
Password to Reply: Decide on password to reply for meet up. For example, PREFER SODA
c) Contribute to the team’s goal by sharing your encoded messages (part a and part b). Please ONLY post part c, the ENCODED MESSAGES, to the Discussion Board.
View example.
Post 2: Reply to a Classmate
Choose one team member’s post that has not yet been replied to. Reply to their post by decoding their message:
a. Using the decoding function, find the decoded numeric values of the message.
b. Using the Numeric Look-Up Table, find the letters associated with those numeric values.
c. Contribute to the team’s goal by sharing the full message in written English.
