Our mathematicians will explore graph theory through an exciting journey to the deepest parts of the ocean where lines, dots, and bubbles come together to reveal the hidden patterns and connections that shape our underwater world.
In this math circle, we'll have the chance to explore a variety of engaging math puzzles alongside Barry, a calm and logical capybara, and Troubblez, an energetic monkey and troublemaker.
Get ready for Barry, the Explorer! He has traveled to the most incredible places and done things beyond anyone's imagination. While exploring a stunning savanna in Brazil, he discovered a fantastic cave adorned with paintings dating back 10,000 years. As he attempted to translate the artwork, he uncovered hidden patterns within it. Will he be able to solve this mysterious puzzle?
In the distant land of Water Dragons there was a magic Dragon called Sphyre that found a strange orbe under one of the most ancient oceans, there was a strange question written there... "Are there numbers between numbers?". This made him so confused, will that be possible? If so, how could that be? Will we be able to help Sphyre to unleash the secret of the magic orbe?
In a faraway land, numbers were born in a specific place, and their positions were determined by strict rules. No one could fathom occupying a different position than the one they were destined for. But one brave number decided to challenge the status quo. Will he succeed in his mission to change the established order, and how will it affect the other numbers?
It is rumored that this island holds hidden treasure, but the path is guarded by a series of cryptic clues and puzzles. Join fellow math adventurers to explore this island!
In the land of Pith, the government is strict, and everything must fall perfectly on the mile-grid lines. But farmer Agrice has a different idea: she wants her farm to be 6 square miles, and be perfectly square in shape, too! Nobody's ever heard of such a thing... Is her dream just a dream, or can we make it a reality?
Squareland is a peculiar place where everything is square, and it’s been like that for so long that its people couldn’t even imagine a different way of being. One day, all of a sudden the dimensional magic button was pressed, and the people of squareland entered a whole new world. Can we help the people of Squareland understand the strange new shapes they’re encountering?
Pascal is a fantastic Monster, he has been doing a great job since he was born, but guess what - things change! He was doing his smashing rocks chore when suddenly he opened a strange hole with a suspicious triangle in right in the entrance. At the very moment that he got in, the whole planet started to melt. Will he be able to solve this bizarre situation?
Ringo and Momo have learned a new number game, but they have very different opinions about it. Ringo thinks it’s boring; it always ends so quickly! But Momo thinks it’s a fascinating puzzle, and she’s convinced there’s a way it can go on forever. Can we help the two friends settle this disagreement?
In this course, we'll ponder a question of the ancients: if Mars and Venus want to exchange letters, how long will it take their messenger to travel between? Considering that we haven't invented trigonometry yet, and both planets lie on the same Celestial Sphere (along with all the other stars, of course!), this question might be a real doozy.
Could we invent a system where all our normal numbers take infinitely long to write, or where our favorite numbers have two different ways to write them? Surely, nobody would ever use such a system! In this course we'll turn place value on its head, and see where the numbers take us.
In this circle, we'll push graph paper to its limits. We'll pursue questions like the following: Can you draw a perfect hexagon on graph paper? Can you draw a square with area 7? Can you draw an equilateral triangle? We'll find out what graph paper is really good for — and what, maybe, it isn't.
Lana was exploring the distant oceans when she came across an ancient tower with a mysterious pattern on the floor. By drawing numbers in the pattern, she got parts of it to light up, depending on the numbers she chose. In this circle, we’ll see if we can help Lana find numbers that light up the whole floor — and then who knows what will happen?
Did you know that 3x4 = 10? (Maybe if we all had 6-fingered hands, we'd all count numbers this way!) Join us as we explore number systems outside the realm of the decimal system we all know and love, and brace yourself for a deep dive from there into the mystery of divisibility rules, both in decimal and in other stranger systems. We'll probably be dipping our toes into number theory and modular arithmetic along the way, but everyone with a firm grasp of arithmetic is welcome in this circle!
What can we uncover about the relationship between surface area and volume of various 3-dimensional shapes? Looking at the ratios there, we will make discoveries about prisms, pyramids, platonic solids, and more. Both examining the geometric elements of these shapes and algebraic graphs of their proportions, we will explore their relationships with each other.
Odds and evens seem like a very simple concept, but there is some deep mathematical exploration lying just below the surface! Join us in exploring parity puzzles involving number theory, combinatorics, and a world of other possibilities!
When we give or get directions to travel, they always start at a known place. But what if we don't know where the traveller is coming from? In this circle, we will explore and create maps that allow us to give universal directions - a list of steps that always end in the same place, no matter where they start.
Water is gradually added to a bucket until it reaches capacity and pours most of its contents into the next bucket. In this circle, we will investigate what happens in this system of buckets over time, looking for patterns that explain when each bucket tips. There is deep mathematics here - more than meets the eye!
Welcome to the enchanting Shape's Island, a magical realm where every geometric form possesses its own special powers. In our circle, we are set to embark on a journey to unravel the wonders of geometry, delving into the intricate and fascinating world of shapes and their unique attributes. Together, we will navigate through the mysteries that make this island a captivating place of exploration and discovery. Get ready to unlock the secrets of geometry in a truly magical setting!
In this circle, we will uncover some unique properties and patterns of polynomials. We will go between different representations of our multi-variable equations and discover real-world applications for these curvy equations.
Some classic problems in the field of Combinatorics have to do with dominoes, and different ways to arrange them. In this math circle, these and similar puzzles will ask us to count — and prove that we’ve counted — the seemingly uncountable.
You are invited to Puzzle Planet, a math circle about algebraic thinking. We will unravel the mysteries and intricacies of algebra, navigating through the terrain of equations, variables, and mathematical patterns. Get ready to engage your mind and unlock the secrets that the Puzzling Planet holds for those eager to delve into the realm of mathematical wonders.
