Long ago, the world was ruled by four powerful Kingdoms: Fire, Water, Air, and Earth. Each Kingdom believed it was the most important and refused to work with the others. Their lands grew apart, and with time, they stopped talking entirely.
But now, a mysterious force is threatening to break the world into pieces. Will the four Kingdoms reunite and solve this strange puzzle?

Dylan has developed a confounding new habit — every time he gets a treat from anyone, he tries to break it into as many equal parts as possible. So, for example, he first breaks a bar of chocolate into two equal pieces. Next, he tries to see if he can break the same bar into three equal pieces, and so on. Sometimes, it is easy to do this. At other times, it feels incredibly hard! He asks his friends for help, and together they try and discover how deep and wide this rabbit hole of numbers goes.
Note - Circle Prerequisites:
(1) Recognizes numbers between 1 and 30
(2) Can count whole numbers
(3) Has not formally been taught fractions
Barry the Capybara is an explorer always chasing adventure and on the hunt for new puzzles to solve. But on the day of his 135th birthday, something strange happened. A magical sphere began to glow in his attic. And when Barry touched it something completely unexpected occurred...
Join our math circle as we follow Barry into The World of Algebra.

How long can we make a sequence game go on? In this circle, we’ll look at an interesting “game” and explore how long we can make different sequences last. We will examine the patterns, and find out if the game is always doomed to end or if we can make it go on forever. What happens if we change the rules? Does it change our outcomes?
Note - Circle Prerequisite:
- Can do subtraction easily
To maximize their lifespan, some mattresses require regular flipping and rotation. This raises interesting questions: How many different ways can a mattress be oriented? Furthermore, can we create simple, foolproof instructions that even our parents can follow to ensure all our mattresses achieve their maximum lifespan?
Note - Circle Prerequisites:
(1) Basic ability to form a logical argument
(2) Does not know about algebraic groups
Long ago, when dragons ruled the earth, four powerful dragons kept the world in balance working together to solve the challenges that appeared on Dragon Island. But one day, everything changed. One of the dragons mysteriously vanished. As darkness spread across the land, the remaining dragons felt their powers slowly fading.
What happened to the missing dragon? Why is the balance breaking? And how can it be restored?

In this circle, we'll take an in-depth look at geometry's favorite shape: the triangle! The features of these shapes extend far beyond what we learn in geometry class, and there's much to discover. Let's draw together, and explore the world of nature's strongest shape!
Note: There are no prerequisites for this circle.
This circle is currently full. Should more participants enroll, we will open a waitlist. To express interest, please reach out to us at info@theglobalmathcircle.org.
Pi is a ratio that allows us to make calculations on a circle, but do polygons have their own versions of pi? In this circle, we will use the circle as a basis for thinking about how to calculate ratios in other shapes. Pi, as we know it, is useful for a radius or diameter, but what happens when we start connecting random points on a circle? This will lead us to the basis for trigonometry!
Note - Circle Prerequisites:
(1) Can use the Pythagorean Theorem
(2) Has not explored the concept of pi beyond circles
We can identify properties of a cube by looking at it, making a net of its shape, or making cuts in it to see what we find. How could we determine the properties of a 4-dimensional cube? What about an n-dimensional one? In this circle, we will explore properties of cubes beyond our visual comprehension. What might we find?
Note - Circle Prerequisites:
(1) Understands properties of 2D and 3D shapes (vertices, faces, lines)
(2) Has not explored this in depth with a hypercube
In this circle, we'll stretch our minds into higher dimensions: how do the shapes there work, and what can we say about them? Join us as we make the unimaginable manageable!
Note: There are no prerequisites for this circle.
In this circle, we will look for paths through a grid of squares. What seems a simple challenge at first can quickly become baffling, as mysterious restrictions on these paths seem to appear. Join us as we grapple with the seemingly-impossible, and learn fundamental mathematical skills along the way!
Note - Circle Prerequisites:
(1) Can count up to 25
(2) Knows about even and odd numbers

Have you ever tried walking carefully on the tile floor of a shopping mall, plopping one foot down on a tile and your other foot on the next? Or maybe you walked diagonally, following the colored tiles, while skipping the white tiles as you shift from side to side.
In this circle we will step through The Door of Imagination into Wonderland, where we become pieces on a vast floor of tiles. We will explore path possibilities as we weave our unique paths on checkered plains, opening up questions geometrical, graphical, and statistical. Come and see!
Note: There are no prerequisites for this circle.
In this circle, we'll use one of math's favorite shapes — the triangle — to dive deep into the world of geometry. Circles and squares have centers, sure! But what about triangles?
