Arithmancy is a magical discipline from the Harry Potter series that studies the magical properties of numbers. In this course, we will use critical thinking skills to work with logic, estimation, secret codes, reduction, predictions, patterns in numbers/art/music, and more!
Meets for 30 minutes once per week for 12 weeks.
Arithmancy is one of Hermione’s favorite subjects at Hogwarts because it is a very precise, measurable, and almost scientific method of understanding the world around her. This is a method of divination by numbers first used by the ancient Greeks. They assigned values to the letters in the names of combatants to foretell the outcome of battles. Later, in the ninth century BC, the Chaldeans in Arabia (where our modern number system also comes from) practiced a form of arithmancy that divided their alphabet into three parts, each part composed of seven letters which they attributed to the then known seven planets. Wizards still use a similar system today, all these thousands of years later.
In this class, we will study the history of Arithmancy and numbers and much more. Pulling from the world of Harry Potter, I’ll introduce logic and fun into a math class that helps learners use critical thinking skills to develop and solve codes, and work puzzles. We will study patterns, and use all this information to predict future events to get all of our Arithmancers ready for the O.W.L. (Ordinary Wizarding Level exam, completed during the fifth year at Hogwarts; in this course, we will simply have a comprehensive review) exam!
