## Teaching experience

For my visit to the Bina Insan Mandiri School on May 11, 2016, I prepared a series of problems to guide students to discover Pick’s Theorem which relates area of a lattice polygon with the number of its interior and boundary points. The target audience I had in mind when writing the worksheet is grade 7 students who had recently learned about areas of plane figures.

On April 28, 2016, I visited a class of fourteen 9th and 10th graders at Medan International School to facilitate an exploration of the shapes of ridges we get by pouring salt on card stocks of various shapes.

On October 25, 2015, Stephen and I organized our first math circle session on two-player mathematical games for middle school students. In running that session for 16 students, we were greatly assisted by math team members Chang, Cynthia, James, Joseph, Louisa, Tan, and Zeno.

I taught classes ranging from Algebra 2 to Linear Algebra at Loomis Chaffee. I also supervised two independent studies.

- 2015-2016: Multivariable Calculus (two sections), Advanced Precalculus (two sections)
- 2014-2015: Linear Algebra, Multivariable Calculus (two sections), Advanced Precalculus (two sections), Real Analysis (spring term independent study)
- 2013-2014: Multivariable calculus (two sections), Algebra 2 (three sections), Set Theory (spring term independent study)

On May 21, 2013, Simon and I gave a presentation for students in an AP Calculus class on the delightful connection between a hat problem, the game of Nim, and construction of codes.

Peter and I organized a Mathematica workshop which was attended by a small group of graduate students during the summer of 2012. We spent most of our time practicing translating our algorithmic ideas into Mathematica code, but we also generated and proved some conjectures based on our experiments with Mathematica.

On May 22, 2011, the Dartmouth mathematics department hosted the mathematics section of the John Hopkins Center for Talented Youths Odyssey Series which was attended by 130 students and their parents. Elizabeth, Enrique, and I designed and led three one-hour breakout sessions on constructive geometry.

I taught two calculus courses at Dartmouth:

- Math 8: Calculus of functions of one and several variables (Spring 2012)
- Math 1: Calculus with algebra (Fall 2010)

Asa, Elizabeth, Katie, Natasha, and I participated in a teaching seminar in the summer of 2010. As part of the seminar, we designed and taught two week-long math camps which were attended by more than 20 high school students each. The topics were “The Four Color Theorem” and “Bijections and Infinity”.

As teaching assistant at Dartmouth College, I led tutorial sessions three times a week and helped grade examination papers for three multivariable calculus courses and one single-variable calculus course.

- Math 14: Calculus of vector-valued functions (Winter 2010, Winter 2009)
- Math 13: Calculus of vector-valued functions (Fall 2008)
- Math 3: Introduction to calculus (Fall 2009)

I was the organizer of the Hanover Chess Club from November 2009 to May 2012. Over the course of that 2.5 years, I had the pleasure of teaching chess on Saturdays to more than 20 children aged 5 to 14. There was an article in the Valley News about our chess club. In May 2011, I designed an introduction to chess problems for a small group of children in grades 1 to 6 for an event organized by the Vermont Council for Gifted Education.
