Martina, The Mermaid
Apply

Martina is no ordinary mermaid, she’s super clever, curious, and absolutely fascinated by machines and dinosaurs! One day, while exploring her favorite corner of the ocean, she discovered something glowing deep in the dark depths. As she swam closer, mysterious shapes and repeating patterns began to appear... and then, out of nowhere, a huge magical creature emerged!

What is this strange creature? What’s the glowing object? And what do all these patterns mean?

Join Martina on an exciting underwater journey filled with mysteries, math puzzles, and magical discoveries. Let’s explore together and uncover the secrets hidden beneath the waves!

The Flying Forest
Apply

The Flying Forest is a magical place where nothing works quite the way you’d expect. No one had ever stepped foot there....until Jolie arrived. Jolie is a curious (and a bit clumsy) treasure hunter who loves discovering odd things like shiny quartz or rusty gears during her hikes.

One day, she stumbled upon a mysterious golden necklace with a tiny wing-shaped pendant. The moment she put it on, she was transported to another dimension! Now, the only way home is to uncover the secret hidden deep in the heart of the Flying Forest.

Join us in this exciting math circle journey filled with puzzles, patterns, and strange forest logic. Help Jolie solve the mysteries and find her way back.

Impossible Dream
Apply

We will explore the difference between “I don’t see how to solve this puzzle” and “No one can solve this puzzle — here’s why.” Can we actually prove that a puzzle is impossible to solve — that no matter how clever someone is or what approach they take, they won't find a solution? Is it possible to prove the impossible?

(1) Has proven something

(2) Has not proven something geometric with parity

Chessboard Ways of Wonderland
Apply

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!

One Way Streets
Apply

We can create systems to get from one place to another using one way streets. Are there times when this is easier to do than others? Times when it cannot be done? In this circle, we will discover what pathways can be created and which cannot, and more importantly, why that is.

Beyond the Third Dimension
Apply

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?

(1) Understands properties of 2D and 3D shapes (vertices, faces, lines)

(2) Has not explored this in depth with a hypercube

Algebra: The Abstract Way (Section 1)
Apply

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!

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!

[CIRCLE IS FULL] Smashing the Skyline
Apply

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.
