Invariants

(3/8/2018) During our course on Invariants, the eight-year-olds spent most of the time exploring the Euler Characteristic (click here for details). This report is essentially a list of other activities we did to start or finish our sessions. An invariant is something that never changes. Piagetian Conservation Tasks – We did every activity in this article: http://www.cog.brown.edu/courses/cg63/conservation.html. Conservation tasks basically…

The Euler Characteristic for Eight-Year-Olds

(Jan. 25 – March 8, 2018) The five students (plus one occasional visitor) in our math circle spent six weeks doing like mathematicians do – savoring a math problem, learning it in depth before any attempts to solve it. I felt like Andrew Wiles in his decades-long work on Fermat’s Last Theorem. BEFORE THE COURSE: THINKING ABOUT IT I didn’t…

Reading Shakespeare for Homeschooled Teens

We had great success of reading Julius Caesar, and the unanimous vote of the participants is read more Shakespeare. This class is perfect for teens who want to experience the sound of reading Shakespeare’s plays outside of the theater.  New participants are encouraged to join us. We start reading Macbeth next week. We have extended the homeschool Shakespeare class all…

Embodied Mathematics

(Nov 2 – Dec 7, 2017) Our 5-7 year olds just spent five weeks experiencing math with their bodies.* You can see some footage of this circle in action on the video we produced during the course. Thanks to all the students and parents who participated. Here’s a list/description of every activity we did.   Role-playing the need for math…

Algorithms, Algebra, and College Admissions

(October 19 and 26, 2017) “Today we’re going to do something we’ve never done in a math circle here. We’re going to take a quiz.” Stricken looks on faces. “We’ll do it together, it’s just 2 questions, and I think it will be fun.” Relief. “I’m always on the lookout for things related to algorithms to share with you, and…

Spotify and Random Number Generators

(October 12, 2017) “Everybody get a partner. Take a piece of paper. Take a pencil. Number your paper 1-30. You’re all going to flip a coin 30 times. In each partnership, decide which person will flip a real coin and which person will flip an imaginary coin.” That got their attention! I needed to harness their attention because many of…

Stable Marriage, part 2

(October 5, 2017) We continued work on the Stable Marriage Problem today. After a discussion of the field of mathematics known as game theory, I put on the board the Jane Austen example that Emily Rhiel used in her Numberphile video. Six students used this example to teach the Gale Shapley algorithm to two students who had not been in…

A People’s History of the United States: The Color Line

We discussed the formation of racism in the colonies and considered the question of if racism is a natural human tendency or a manufactured institution.

The Stable Marriage Problem (Gale Shapley Algorithm)

(October 2, 2017) I discovered this problem and was so excited – my students would love it, it directly tied in to the topic of our course, and it was a good example of a mathematical algorithm that all of the students would have sufficient math background to work. I wanted to do it right away, so I discarded my…
