In this project, the students calculate a series of matrix operations and present the solutions in a specified manner on a poster suitable for display on the classroom wall.

The project includes an optional story (essay) because some school districts encourage English across the subject spectrum as a way to improve overall student language skills. You may choose to require the student to write the story, as described in the project description. Or, you can change the points assigned and make the story an extra credit portion of the assignment. Or not assign it at all.

The project is intended to raise awareness, at least a bit, of the efforts of Alan Turing and his post-war plight. His plight and success during World War 2 was dramatized in the movie The Imitation Game, starring Benedict Cumberbatch as Alan Turing.

This project allows the student to create any message, and then to create the matrices to encode and decode the message. Since the student is defining her/his matrix, there is no single answer to the project. The grading of the project therefore requires that you (the teacher) perform the matrix inversion and matrix multiplication to verify each student's work (but it is only a 2 x 2 matrix). Therefore, there is a bit of work in the grading process for this project. Additionally, if the story is assigned, it should be graded only insofar as to completeness and creativity, and never on grammar.
