On a Mission

By | Uncategorized

Last week MC2 completed a six month strategic planning process. In three years we plan to double in size, expand our summer camps, all while maintaining the quality of our programs. We’ve also refined our mission and our values:

The mission of the Math Circles of Chicago is to create opportunities for all children across Chicago to develop a passion for mathematics.

Core Values
1. Math should be fun and empowering
2. Every child can do and enjoy rich math
3. Every child deserves equitable access to these experiences
4. Students should be the agents of their own learning
5. Math can and should be a cooperative endeavor

In the context of over-testing and competition, this mission and these values resonate. Mathematics shouldn’t be seen as a chore; it shouldn’t be for the few; in the real world, it isn’t an individual endeavor. Our mission is to create opportunities for a better mathematical experience.

Math Circles of Chicago achieves its mission by providing free, unique math enrichment programs for 5th–12th grade students of diverse backgrounds. All Chicago, every kid, amazing math.


New at MC2!

Math Circles of Chicago is serious about its commitment to provide all kids in Chicago access to fun, confidence building, novel math. In turn, we are always trying to expand, experiment, and improve!

  • Morgan Park    Our 7th site opens this fall. Morgan Park is on Chicago’s far south side, 10 miles from our closest site at UChicago, so we hope to recruit a new crop of kids who couldn’t come to MC2 before! We will hold Haynes (5th/6th grade) and Brahmagupta (7th/8th) sessions at Morgan Park High School on Monday afternoons. We are also trying another experiment–weekly sessions (elsewhere we meet bi-weekly).
  • Bridgeport Expansion    For several years we’ve held MC2 sessions at Benton House in Bridgeport. That site only had one classroom, so we’re moving to a new location–St. Therese on 23rd St. This move will allow us to expand to three groups of students, Haynes, Brahmagupta, and Cantor (Algebra 1/Geometry students). 
  • Summer Camps    Through the generous support of the CME Group Foundation we’ve held brief summer camps the past two years. We are taking a serious look at expanding and lengthening these camps, making them permanent, and announcing them earlier in the year to make it easier for families to plan to attend. Expect a formal announcement in December.
  • Homeless Shelters    Last spring we started holding math circle sessions in a local shelter, and this work continued this summer at a 2nd location. This upcoming year we will be leading sessions in up to three shelters.

We’re proud to say that all of our programs have remained free as we’ve continued to grow. We’ve been able to do this through generous support from families, foundations, and many volunteers. Thanks to everyone–we’re looking forward to another great year!


Math, Guitars, and a House of Cards

By | Uncategorized

Last week the New York Times published, “Make Your Daughter Practice Math. She’ll Thank You Later. The way we teach math in America hurts all students, but it may be hurting girls most.

It’s the sort of article that leads me to write a Comment, but many people beat me to it. Typical were responses about a father forcing the child to memorize times tables, which the child resented at the time, but boy was dad proud the day that PhD was earned (this Comment was an ‘NYT Pick’).

The editorial compares learning math to learning a musical instrument. Just like learning to play the guitar, “Simply understanding how a chord is constructed isn’t the equivalent of being able to play the chord….The word “rote” has a bad rap in modern-day learning”.

The piece argues that math teaching places too much emphasis on conceptual understanding, and not enough on the kind of drill that makes reciting times tables automatic.

The problem is that the author here doesn’t take the analogy far enough. True, the goal of playing a guitar is not understanding why a chord is a chord, but the goal of playing a guitar is also not playing chords.

The goal is to make music.

So what’s the object of doing math? It’s not doing times tables. It’s conceptual understanding itself.

Now, I don’t actually disagree that kids need to be fluent mathematically, just as there is value in learning to play individual chords on a guitar as a route to playing a full piece. But memorizing times tables is actually the equivalent of memorizing where your fingers go rather than actually placing those fingers properly on the fret board.

So how do you learn to ‘play’ math the right way?

What is 9 x 7? 63. How do I know this?

  • 10 x 7  is 70. To get 9 7’s, 70 – 7 = 63.
  • 5 x 7 = 35 and 4 x 7 = 28, and 35 + 28 = 63.
  • 10 x 10 = 100. 9 x 11 = 99. 12 x 12 = 144. 11 x 13 = 143. I see a pattern. Since 8 x 8 = 64, multiplying 1 less than 8 by 1 more than 8 is 63. Later in Algebra I’ll be able to connect this to the full generalization that (x + 1)(x – 1) = x^2 – 1, a special case of what’s called a, “Difference of squares.”
  • It’s 63 because I have it memorized.

The memorization came after I made connections. This result fit into an overall structure, with the truth of any one piece fitting into a larger picture. And, moreover, it fit into a future picture. When it came time for Algebra, my experience learning arithmetic fit. I didn’t go on to memorize the distributive property and the difference of squares pattern, I connected them to prior learning.

“Rote” has a bad rap in modern math learning for good reasons. The article goes on to say, “But girls especially could benefit from some extra required practice, which would not only break the cycle of dislike-avoidance-further dislike, but build confidence.”

My 25 years of teaching experience tells me the opposite. When students learn by rote, they are two years away from never being successful in math again. When the math you know is a disconnected, unstructured house of cards, you don’t know when it will fall apart, but you know that it will.

Sounds Like They Might Be Talking About MC2

By | Uncategorized

In Deborah Peart’s recent essay on Edutopia, she makes the following points about kids’ development of math identity:

  1. Math experiences need to be about more than just numbers.
  2. Math needs to be a positive experience for kids.
  3. Children should be the agents of their own learning.

To which I would say–sound familiar ? MC2 is an organization that promotes (1) Allowing kids to experience novel mathematics to (2) build a life long love of math where (3) they may ultimately participate in QED, our math symposium, and present research on a problem they themselves created!

Those interested in MC2 should also check out Hilde Kahn’s post, “Closing the Excellence Gap,” on FutureEd. “If we’re really serious about increasing the number of low-income students and students from underrepresented groups who are learning math at the level required to contribute to our increasingly computational world, we should take a page from the playbook of those who are already successful: We should provide high-quality math enrichment for many more kids, as early in their educational lives as possible.”


So, if you haven’t signed up already, it’s time to register your 3rd to 8th grader for our June 2nd Julia Robinson Math Festival. Our friend and colleague Eugenia Cheng just let us know she’ll be there to run a table! (And you should check out the new book, Power in Numbers: The Rebel Women of Mathematics by Talithia Williams, featuring none other than Dr Cheng herself!)

Free, high quality, for all kids. Sounds like they may be talking about us.

  • The Mathematical Association of America announced that for the 3rd consecutive year it will be giving MC2 an award!
  • The Springboard Foundation renewed (and doubled!) its funding for MC2, which will support our opening a 7th site in the fall!
  • MC2 is coordinating a free mini-camp that Eugenia Cheng will hold for local high school students. In addition to her many achievements, Planet Money fans should listen to her talk about infinity on yesterday’s Indicator Podcast.
  • The Illinois Council of Teachers of Mathematics announced that Sendhil Revuluri will be given this years Lee Yunker Mathematics Leadership Award. Sendhil is a current and founding Board Member of MC2, and his leadership has been essential in MC2’s development into a premier free and accessible math circle for kids across Chicago!


Free Eugenia Cheng Summer Mini-Camp for High Schoolers!

By | Uncategorized

Join Dr. Eugenia Cheng as she leads three afternoon workshops from July 23rd to the 25th! This program is free and any current student in grades 9-12 can apply.

Dr. Cheng is an internationally famous mathematician, author, pianist, and chef! Her books include How to Bake Pi and Beyond Infinity, and she regularly writes for the Wall Street Journal; check out her Ted talks and appearance on the Stephen Colbert Show on Youtube. Currently she is the scientist in residence at the School of the Art Institute of Chicago.

From Dr. Cheng:

“Math isn’t just about numbers and equations.  It’s not just about solving problems or getting the right answer. So what is it about?  In this mini camp we will explore high level abstract math in an open-ended and accessible way, particularly appealing to visual and hands-on learners. We will emphasize creativity rather than following rules, discovery and investigation rather than facts, choices and possibilities rather than right and wrong, and structures to be built rather than problems to be solved. We will delve into some abstract mathematics typically only seen in grad school, or in advanced undergrad math classes, but which I have been teaching to art students at SAIC for several years.  In the process we will see how math helps us think more clearly about anything and everything in the world around us, with specific examples including questions of social justice including tolerance, privilege, prejudice and equality. Thus we will see that “abstract” doesn’t mean “irrelevant”, but rather, that abstract thinking can help us understand urgent issues in the world around us. The only prerequisites are curiosity and an open-mind about what math really is.”

Program Information:

  • The Mini-Camp will be held from 12:30PM-3:30PM on July 23rd, 24th, and 25th at Payton Prep, 1034 N. Wells.
  • 20 students will be invited to attend.
  • To apply, students must complete the lottery registration at www.mathcirclesofchicago.org/register along with the google form at www.tinyurl.com/mc2eugeniacheng2018. You will need to provide a math teacher’s name and email address as a reference, along with a short statement about why you would like to attend.
  • Complete the application by May 18th; we will begin to notify students about admission on May 20th.
