Ages: 9-10

Students will be exploring Number Theory in our November-December Math Circle. We’ll start out with place value, and will probably end up getting into different bases, such as binary. We’ll also likely explore infinity: What is it? How big is it? Is there only one type of infinity? Throughout this, we’ll collaborate to discover what it really means to “borrow” and “carry,” both arithmetically and algebraically. (No formal algebra knowledge is required for the course, though.) This will all be done within the framework of a really interesting accessible mystery, so there’s no need to tell your kids what the underlying conceptual topic is. It’s much more fun for them to invent and discover math for themselves.
