Step into a world of number grids and unravel their hidden secrets. Join us as we explore the mysterious relationships between numbers that create harmony out of chaos. Using logic, creativity, and a bit of mathematical wizardry, we’ll discover how to organize numbers in surprising ways that have fascinated mathematicians for centuries.

Note - Circle Prerequisite: Does not have experience with magic squares beyond 3x3

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: There are no prerequisites for this circle.

Platonic solids have much more in common than just being made up of all one shape, but how do we know what their relationships are? In this circle, we will explore these particular shapes in detail: their relationships with each other as well as how they connect to others. In doing so, we will discover why they make up a cohesive set and derive equations based on them.

Note - Circle Prerequisites:

(1) Should be familiar with volume and area equations for a variety of 3-D shapes

(2) Should have comfort manipulating algebraic equations

The great mathematician, Ramanujan, was fascinated by Magic Squares. There is so much more magic to be discovered! This circle will explore various magic shapes, possibly going beyond numbers. Give your child the chance to fall in love with a subject that's full of creativity, challenges, and, yes, a little bit of magic.

Note - Circle Prerequisites:

(1) Fluency with addition

(2) Has not extensively studied magic shapes, such as magic squares

In this circle, we'll make geometry pop out of the page, and explore the third dimension! What shapes can we make, and what are their characteristics? We'll follow the rabbit holes of mathematics to a variety of exciting potential destinations, from graph theory to the wonders of dimensions higher than 3.

Note - Circle Prerequisite: Has not studied graph theory extensively

This special one-session circle is a chance to experience the engaging and collaborative nature of math circles and discover whether it’s the right fit for your child.

Participants will be grouped according to age and math level to ensure a positive and meaningful experience.

Note: This circle is exclusively for those who have not yet participated in math circles run by The Global Math Circle.

The mysterious number Pi shows up all over mathematics. But where does it come from, and how could we calculate it from scratch? In this circle we’ll travel back in time and tackle the mystery the way ancient mathematicians did, using only geometry. We’ll build and analyze triangles inside a circle, explore the Pythagorean Theorem from the ground up (no prior knowledge needed!), and use these tools to get closer and closer to Pi. Along the way we'll be able to connect our work to real‑world questions like estimating the distance the Earth travels around the Sun.

Note - Circle Prerequisite: Comfort with square roots

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?

Note: There are no prerequisites for this circle.
