Title: Code Breakers Project Idea: You are an agent of the National Security Agency (NSA). Your job is to crack coded messages that are intercepted. Your unit just received a message from a well-known terrorist group. The message is thought to reveal the exact location of the next terrorist attack on the United States. Your elite “Code Breaker” unit needs to crack the code, find the coordinates, and send a coded message to your supervisor who will send it to the President, FBI, Pentagon, and the Response Unit of Homeland Security.
Entry Event: A member of National Security Agency or a similar person will come and talk about terrorism, jobs related to the fight against terrorism, and launch the project idea.

Habits of Mind1. Make sense of problems and persevere in solving
them. 2. Reason abstractly and quantitatively.3. Construct viable arguments and critique the
reasoning of others. 4. Model with mathematics. 5. Use appropriate tools strategically. 6. Attend to precision. 7. Look for and make use of structure.8. Look for and express regularity in repeated
reasoning Look for and express regularity in repeated reasoning
Proficient students clarify the meaning of real world problems and identify entry points to their solution. They choose appropriate tools and make sense of quantities and relationships in problem situations. Students use assumptions and previously-established results to construct arguments and explore them. They justify conclusions, communicate using clear definitions, and respond to arguments, deciding if the arguments make sense. They ask clarifying questions. Students reflect on solutions to decide if outcomes make sense. They discern a pattern or structure and notice if calculations are repeated, while looking for both general methods and shortcuts. As they monitor and evaluate their progress, they will change course if necessary.

See Map the Project Flowchart.Before you start this project, ensure the computer lab is reserved for the necessary lab days. Contact the National Security Agency person about the date the project will be launched. Gather the necessary materials to make the packets (see materials list above). When you copy the cover letter, place your name under “Sincerely” because you are the liaison. You know your students and how they interact with one another. Place your students into National Security Agency Units. These units should be in groups of three and no more than four students each. Make certain that the units have diversified members according to tiering and other collaboration criteria that the teacher chooses. The Agent Notebook Entries have 2 versions. One copy is for students that are capable of taking notes off a website and the other copy is for students who need the extra help/support to guide them throughout the note taking process. Keep this in consideration while making the copies to place in the packets. On each Homeland Security Packet (use a large manila envelope), write down the unit agents names on the outside. Inside the packet, you will need to place 1 Cover Letter, 1 Map of United States, 1 coordinate grid transparency, Agent Notebook Entry 1 (one for each agent), Agent Notebook Entry 2 (one for each agent), Agent Notebook Entry 3 (one for each agent), 1 National Security Agency Document 1, 1 National Security Agency Document 2, Tech or No Tech? (one for each agent) and regular envelope. For the coordinate grid transparency, use a 1 centimeter coordinate grid paper.The cover letter will explain the culminating project and the steps that the unit will have to take to ensure national security. (At this point make sure you have read the cover letter. The teacher will be the supervisor that will act as the liaison between the NSA Unit and other agencies.)Task 1: Launch the ProjectTo launch the project, introduce the National Security Agency individual who will talk with the students about NSA, the fight against terrorism, and the jobs that are available in this field. At the end, he/she should pass out the Crack the Code packets to each unit. Have each unit read the cover letter. Hand out the Checklist. The teacher will explain how they should use it to keep themselves and their NSA Units on task and to meet all deadlines which the teacher will announce to them throughout the project. Task 2: Computer Lab and Agent Notebook Entry 1Students will learn about matrices, parts of matrices, and how to perform operations with them in Agent Notebook Entry 1. Students will go to the computer lab and visit the specified web-sites that are on their entry sheet. If a computer lab is not available, project the web-sites. This can be done as an individual assignment or depending on the student’s ability may work with another student. Circulate throughout the room to answer questions and keep students on task. When all the students in each individual unit are finished filling out their Agent Notebook entry, pull them together and have them compare and discuss the answers. When they feel they are ready, give the unit their next task. Depending upon your overall class ability level, you may want to spend one day on adding, subtracting, and scalar multiplication then go on to the Teacher Choice Assessment. After they master those concepts, go back to the websites and do the multiplication of matrices and finish up Teacher Choice Assessment 1.Task 3: Teacher Choice Assessment 1Students will find various specified cities on a map; find their ordered pair using the coordinate grid, then determines the slope between the cities and Washington, D.C. in the National Security Agency Document 1. Have the students place the coordinate grid over their map like you would stack two sheets of paper together. The NSA Units will fill out the National Security Agency Document 1. Have each agent work the slope problems on a separate sheet of notebook paper. Transfer the slope answers that they agree upon on to National Security Agency Document 1. By working in their units, cooperative learning can take place. It is very important that the answers are correct so they can write equations in National Security Agency Document 2.The students learned about matrices and how to add, subtract, and multiply them during Agent Notebook Entry 1. The teacher may want to break down this task into adding, subtracting, and scalar multiplication of matrices as one assignment and multiplying matrices as another. If you break it down, you may need more than one assessment. Use any assessment of your discretion to evaluate their knowledge. This assessment could be a worksheet, problems from the textbook, etc. Grade according to whatever criteria you choose. Task 4: Computer Lab and Agent Notebook Entry 2Students will learn about determinants in Agent Notebook Entry 2. Students will go to the computer lab and visit the specified web-sites that are on their entry sheet. If a computer lab is not available, project the
web-sites. This can be done as an individual assignment or depending on the student’s ability may work with another student. Circulate throughout the room to answer questions and keep students on task. When all the students in each individual unit are finished filling out their Agent Notebook entry, pull them together and have them compare and discuss the answers. When they feel they are ready, give the unit their next task. Task 5: Teacher Choice Assessment 2Students learned about determinants in Agent Notebook Entry 2. Use any assessment of your discretion to evaluate their knowledge. This assessment could be a worksheet, problems from the textbook, etc. Grade according to whatever criteria you choose. Task 6: Computer Lab and Agent Notebook Entry 3Students will learn about identity and inverse matrices in Agent Notebook Entry 3. Students will go to the computer lab and visit the specified web-sites that are on their entry sheet. If a computer lab is not available, project the web-sites. This can be done as an individual assignment or depending on the student’s ability may work with another student. Circulate throughout the room to answer questions and keep students on task. When all the students in each individual unit are finished filling out their Agent Notebook entry, pull them together and have them compare and discuss the answers.

Use any assessment of your discretion to evaluate their knowledge. This assessment could be a worksheet, problems from the textbook, etc. Grade according to whatever criteria you choose. Task 8: Cryptography and Matriceshttps://www.sascurriculumpathways.com/portal/Launch?id=293 - Students explore a real-world use of matrices and their inverses. They encrypt and decrypt messages using alphabet assignments and 2x2 and 3x3 matrices, as well as, research and document another real-world use of matrices.Task 9: Crack the CodeCollect Tech or No Tech? writing assignment for assessment.Each NSA Unit will write a different code that another unit will break. After each unit has written their message which includes the targeted city, have them place it in an envelope. Each unit will pick a different envelope. Once they “crack the code”, they will write the answer in a different code that the first group will decipher. They will need the information from their National Security Agency Document 2 to help them crack the code and write their return code. Task 10: Evaluation and ReflectionEach student will fill out a Student Reflection and each NSA Unit will fill out a National Security Agency Unit Evaluation. The teacher will fill out a Teacher Reflection.
Dear National Security Agency Unit,
Your elite “Code Breaker” unit was chosen to break an intercepted code that is believed to include the coordinates of the next city targeted by a well-known terrorist group. The FBI has managed to place one of its operatives in the group which has reported back with very reliable intel. The terrorist group does not believe in technology because of their religious beliefs so the group is using mathematical matrices to write its codes.
Your unit is to learn about matrices so that it can crack the code. Give your supervisor the coordinates to send to the FBI, the Pentagon, and the White House. They will pass it on to the Response Unit.
Thank you in advance for your patriotism and helping keep our great country safe.
Sincerely,
Map of United States

Crack the Code
You are an agent of the National Security Agency (NSA) whose job is to intercept and crack coded messages. Your unit just received a message intercepted from a well-known terrorist group. The message is thought to reveal the exact location of the next terrorist attack on the United States. Your elite “Code Breaker” unit needs to crack the code, find the coordinates, and send a coded message to your supervisor who will send it to the President, FBI, Pentagon, and the Response Unit of Homeland Security.
For the first part of this task, your unit will play the “terrorist” part and write a secret message that contains the targeted city that another unit will decode. Your message needs to reveal the equation of the “targeted city” that YOUR UNIT chooses. Use the equations your unit wrote in the National Security Agency Document 2. After another group decodes your message, they will write a new coded message that your unit will translate to check their answer of the city they think is the target.
To write your coded message, make up a problem that has a value between 1 and 26. That value will be where you will start your alphabet order. The problem can be any type of problem you have studied in this project. For instance, determinants or operations of matrices.
For example:Find the determinant.
8 10 = 88 – 70 = 18
7 11
So A will start at position 18.

Your message should include the equation of the city your unit chose. When you write the code, there is to be one space between each number and 2 spaces between words. Place numbers that are in the equation in parentheses.
For example:
26 18 4 (12) 16 22 18 9 10 6 3 21.I A M 12 Y E A R S O L D .
