Course Description

Do you love puzzles and codes? Have you ever wondered what their history was? Do you think you’re good at solving, codes and puzzles? Do you like to speculate about mysteries?

n this interdisciplinary social studies class, we’ll learn about the history of secret codes from the earliest ciphers to modern cryptography. We’ll see how Julius Caesar used codes, how a secret code helped Queen Elizabeth I maintain her throne, and how British cryptography experts broke a Nazi code machine. We’ll also explore some of history’s most infamous mysteries, such as what was a mysterious machine from ancient Greece really used for and what happened to the Lost Colony. We’ll look at ways science can solve some historical mysteries we thought would always be unknown.

Along the way, we’ll hone our problem solving skills by creating and tackling lots of codes and puzzles. We’ll talk about specific problem solving strategies. And at the end of the course, one student will win a prize for being the top code breaker and puzzle solver.

Course Structure

We’ll explore history with two units. The first will cover secret codes. The second will focus on great historical mysteries. In the first unit, we’ll have a single book. Students will need to read one chapter per week. In the second unit, we’ll have a variety of readings that I’ll provide. Each unit will have a class presentation and a writing assignment.

In addition, we’ll have a weekly codes and puzzles contest. Students will get points for attempting the secret codes and more points for solving them. Once time is up to submit solutions, we’ll discuss solving strategies in class each week.

Who should enroll?

  • Students who love to tinker and solve codes
  • Students looking for an outside the box social studies class
  • Students who like math and science mixed with their social studies
  • Students interested in learning some nonfiction reading skills

Technology Requirements:

  • High speed, broadband Internet
  • Sound card and microphone (for live sessions)
  • Students may be asked to scan or take pictures of certain assignments for submission
  • Technology such as PowerPoint or Google Slides will be useful for class presentations

Evaluation and Feedback

My goal as an educator is always to help your student move forward in their skills, whether those are in writing, speaking, or critical thinking. I give detailed feedback on writing and presentations to help students grow in their skills.

Because we’ll be solving codes, the most important element is participation and attempts. Students will get bonus points for correct solutions and cleverly made codes, but grades will primarily reflect class discussion and completion of assignments.


Communication is through Canvas. Parents and students are encouraged to reach out. Additionally, I provide a short narrative report about your student’s performance at the end of the semester.

Required Texts

The Code Book: The Secrets Behind Codebreaking by Simon Singh

Please note that this is the young reader’s edition of Simon Singh’s adult book with the same title. Our edition has a blue cover. It has the ISBN-10: 0385730624. Don’t mix it up with the adult book, which has a tan cover and is probably too much for many students to handle!

All other readings will be provided.
