# Mark's Handouts

[ORMC]: https://circles.math.ucla.edu/circles

This page lists all the handouts I've written for my classes at the [ORMC],
arguably the best math circle in the western world. We teach students mathematics
far beyond the regular school curriculum, much like [AOPS](https://artofproblemsolving.com)
and the [BMC](https://mathcircle.berkeley.edu).

<br></br>

{style(color_var:pink) For my students: } \
Don't look at solutions we haven't discussed,
and don't start any handouts before class. That spoils all the fun!

{style(color_var:green) For everyone else:} \
If you're using any of these, please let me know---especially \
if you find errors, mistakes, or a poorly designed section. \
Such things must be fixed! { include(email_beta) }

<br></br>

## Overview & Context

Our classes are two hours long, with a ten-minute break in between. The lessons below
are written with this in mind.\
I do not expect the average student to finish all problems during this two-hour session.
If the class finishes early, the lesson is either too short or too easy.

## Warm-Ups

Students never show up on time. Some come early, some come late. Warm-ups
are my solution to this problem: we hand these out as students walk in,
giving them something to do until we can start the lesson.

## Advanced

The highest level of the ORMC, and the group I spend most of my time with.
Students in ORMC Advanced are in high school, which means
they're ~14-18 years old.
