This year we will be starting off with a great worksheet filled with a variety of problems, and we will go through it in teams in competition. cant wait!

Many nontrivial Olympiad problems can be solved by angle chasing. This class we covered inscribed angles, cyclic quadrilaterals, and properties of the orthocenter.

We will return to the fair share problems that we introduced in week 1, by considering what happens when we have to divide among three people. We will also think about the geometry of plane figures and how many places lines will intersect with different figures.

We will be developing logic skills by looking at problems with different colored hats. The goal of this handout is to learn how to make an assumption, test the assumption, and readjust the original assumption if necessary.

The Fundamental Theorem of Algebra... Everyone's heard of it. If it's so fundamental then why haven't we seen a proof?! Look no further, we consider complex polynomials and graphing techniques to prove that every complex polynomial has a root.

This week, we'll continue with our exploration of Egyptian Multiplication and Binary Numbers. If we have additional time, we'll go through the Math Kangaroo problems.

Today we will be starting on one of the most interesting and important topics in mathematics, at least in my opinion. I hope everyone learns something!

To start off the new year we are going to split the class into two competing groups. There will be a variety of problems to work on and it will be up to the teams to organize how they feel is best.

We will go over the winter break geometry homework and review last quarter's material, and do some Olympiad problems from other subjects if time allows.

This week, we'll take a deeper look into what happens when we multiply negative numbers and use what we learn to further our exploration of exponential functions.

Today we will be investigating some ideas in probability in combination with some familiar ideas in geometry. We think today's handout will be great for those that found our previous topics less than exciting compared to usual. We hope that these probability problems will be a good change of pace!

We introduce the concept of metrics using a motivating example: the taxicab metric. This worksheet is especially useful for all those of you who are part time students and part time taxi drivers in New York City.

We introduce the taxicab metric, a new way of measuring distance in Euclidean space. We will study its properties and figure out how it relates to the Euclidean metric.

This week, we will begin by working through the remaining math kangaroo problems in the packet. Afterward, we'll begin our exploration of the world of polyhedra.

Hello everyone! This week we will be working on some problems that have to do with number theory! Number theory is a very important subject in math and is considered one of the most difficult!

We use the first part as motivation to define metrics in general. We talk about a few different examples and introduce the notion of convergence of a series.

We generalize different notions of distances, as motivated by the taxicab distance, into something called a metric space. We then discuss convergence of sequences in metric spaces.

This week we are continuing our problems on the Chinese Remainder Theorem (CRT) along with a small introduction to ‘if and only if' proofs within the context of remainders and divisibility.

In economics, the Gini index is a measure intended to represent income inequality. We will take a mathematical approach to the study of the Gini index.

This week we are continuing some more on divisibility with problems around the greatest common divisor as well as Euclid's division algorithm. The handout is attached below.

Students will learn what an error of measurement is and how the said error propagates through computations that use the result of the measurement. In the process, the students will derive the sum, product, and quotient rules for the derivative using an engineering approach instead of taking limits.
