Dash is a curious explorer who has always been captivated by the mysteries of the Amazon. One day, while exploring the great rainforest, Dash stumbles upon a peculiar stone covered in geometric patterns and cryptic diagrams that look like a maze, which hint at the existence of a hidden temple deep within the jungle. Dash must solve puzzles involving tessellations, symmetry, and angles in order to uncover the path to the temple. Will you join Dash on this journey to unlock the secrets of The Hidden Temple?

Tiago, a boy who has always hated books, finds himself unexpectedly trapped in a library. He had to spend the night there, which he found truly boring, but then all of a sudden he saw a book glowing with a strong blue light. When Tiago opened the book, a great wind started and everything was twirling super fast. He did not know if he should be excited or frightened. When the wind died down, there were strange patterns written in neon ink all over the library. What will happen to Tiago? What and who put those patterns there? Embark with us on this intriguing adventure.

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.

Barry, a brave and clever capybara with a love for math mysteries, embarks on an exciting journey to The Island. Barry likes puzzles that involve connecting spaces, such as finding paths through mazes, solving bridge-crossing challenges, and uncovering hidden patterns in graphs. One day, while exploring a dense forest, Barry stumbles upon an ancient map that leads to a cave called The Chaos Cave. Will you join Barry in solving this spatial puzzle and uncovering the secrets of the ancient map?

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

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 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!
