Office hours: Malott 218, Wed 1.15 pm -- 2.15 pm, Thu 5.15 pm -- 6.15 pm.
Here is the official course page.
Here is the review worksheet on the material of Chapters 1 and 2, and solutions to the problems:
Sometimes on Fridays, when I don't feel like lecturing and the students are too tired to listen to me (after all, it's Friday afternoon),
I give them problems to work on. Below are the problems sets and some of the solutions.
On Friday October 14 we had a fun activity in class. First part was not fun: we had a quiz (thanks to Amin Saied for making it).
Then, I asked the students to form small groups (about 3 people per group)
and grade the solutions for the same quiz that I made up myself (each quiz problem has two different solutions, separated by a vertical line).
Each group of students was supposed to fill in a questionnaire about the solutions presented.
Below are some more Friday problems:
Below are practice problems and they won't have solutions. These problems might be a little bit harder than the textbook exercises,
and I don't know how well they will approximate the difficulty of the problems on the final exam. But if you want a little bit more practice
then here you go:
My office hours will be held in Malott 218 on Mondays and Wednesdays, 5.00 to 6.00 pm.

During Fall 2015 I am teaching one of the three mini-courses in Ithaca High School Math seminar. I will be talking about groups of symmetries.
Two other graduate students teaching a mini-course this year in the seminar are Sergio Da Silva and Daoji Huang.
At the end of the year students were presenting their research projects. There is an article on the Cornell Arts&Sciences college news page about the event. Here is a picture of all the participants.
As a research project, Zachary Stillman and Bowen Shan were studying symmetry groups of Ribik-type puzzles. Here are the slides from their presentation:
Below are the slides from the lectures, as well as a few problem sets the students were offered to solve.
The main source that I used heavily is the following amazing notes by Pavel Etingof:
Other very useful references were:

The problems from the discussion sections:
These are the materials for a mini-course about algebraic topology I taught in IHS in the Fall of 2014. Please, let me know if you have comments/suggestions/complaints.
I was using a few sources, the main ones being the following wonderful books and articles:
In Spring 2012 Alexander Minets and I were teaching an informal introductory course on Algebraic topology for undergraduate students in Belorussian State University. Below are the weekly problem sets (in Russian).
Our main references were:
