Drew is a 6-year-old girl who has recently been put in charge of her class at school. One day, instead of the usual lunch given by their teacher, Drew is given one ginormous sandwich to divide amongst her friends! Drew discovers that this is now the rule - every day, their teacher gives the class one huge piece of food to divide, and it's getting very tricky. How is she going to divide everything into equal parts for all the kids in her class? 

Drew, however, is not one to give up. She's determined, caring and clever!

Godzilla: Destroyer of cities or misunderstood architect? Godzilla has a unique hobby: demolishing buildings and creatively reconstructing them like Legos. This "smash and rebuild" cycle repeats over and over.

This circle will delve into the long-term effects of Godzilla's "renovation projects" with a mathematical lens to study and ultimately predict the fascinating patterns that emerge from Godzilla's seemingly chaotic endeavors. Through this exploration, we'll gain insights into the surprising order that can arise from chaotic events and discover the elegance of mathematics in modeling even the most fantastical scenarios.

Padma the Painter wants to start her own line of paints, but she knows that to be successful, she needs to offer a variety: her goal is to start by selling 100 different colors! As we work to help Padma plan her business with the limited equipment she has available, we'll find ourselves diving into the world of counting and combinations: the rich mathematical world of combinatorics.

Note - Circle Prerequisites:

(1) Mastery of basic multiplication

(2) Has not studied combinatorics extensively

Let's say a teacher wants to divide their students into small groups for each class, and wants the groups to be different every time. How long can they teach their course for before they have to re-use groups? This question, and the expansive world of combinatorial explorations it leads to, will be the focus of our circle. It'll be an exciting dive into a fascinating and creative subject area!

Note - Circle Prerequisites:

(1) Solid multiplication skills

(2) Does not have extensive experience with combinatorics

Have you ever thought about what the basic arithmetic operations really are? Is there a reason why addition, subtraction, multiplication, and division are the most common operations that we use? What if we invented new operations? And what if these operations could work on objects that aren't even numbers? Join us as we discover an abstract world of the algebra and arithmetic we thought we already knew!

Note - Circle Prerequisites: Has completed Algebra 1 or equivalent

Musa loves mandazi! One day, he had some delicious mandazi, each decorated with a special number. He arranged them neatly in a well-organized mandazi holder. But Musa wasn’t done yet — he decided to play a little math trick! After having some fun, Musa ate all the mandazi (yum!) and left behind only the empty mandazi holders.

Now, it’s your turn to become a Mandazi Math Detective! Can you figure out where Musa originally put the mandazis?

Note - Circle Prerequisites:

(1) Experience with multiplication

(2) Experience with the concept of factors

In this circle, we'll start where we left off in A Change of Pace, and continue exploring the exciting and challenging topic of Calculus! Topics will depend on where we leave the previous course, but may include finding funky slopes and the volumes of crazy three-dimensional objects!

Note - Circle Prerequisites: Completion of A Change of Pace or Calculus from Scratch, or consult with leader

Let's say we have a finite number of points (at least two) in the plane and they're not all in a line. Is it possible to arrange them so that you can't draw a line that passes through only two of the points? How (or, why not)? Join us as we tackle this and other difficult geometry challenges!

Note - Circle Prerequisites:

(1) Completion of pre-algebra

(2) Familiarity with solving algebraic equations and simplifying fraction expressions with variables

This is a follow-on circle from last semester's Calculus from Scratch. Join us to uncover some even more powerful techniques in calculus, and to delve into even more new territory! What we cover will depend on where we leave off in the previous circle, but we may be exploring the behavior of functions as they approach infinity, calculating the volumes of crazy 3D shapes, and more!
