Fall Registration is Open!   

Our lottery ran on Saturday, 9/19. Remaining spots are instantly available on a first come ,first serve basis, so register ASAP.

Note that:

  • We had an exceptionally large number of students apply for our Brahmagupta-7/8 program. Our Saturday afternoon (UC & Payton) and Thursday after school (Lane Tech) programs are full at that level. There are spots availalble in our Saturday morning (Back of the Yards) site, as well as a few spots at our Monday and Tuesday afternoon sites (Morgan Park and Bridgeport). For those Brahmagupta-7/8 students on a waiting list, we recommend joining one of these sites just mentioned. 
  • Our Saturday afternoon Cantor-A1/G sessions also filled; there are still openings at our Saturday morning (Back of the Yards) and Thursday afternoon (Lane Tech) sessions.

Our fall programs will be online--learn more details here. You might also want to sign up for our monthly email newsletter to make sure you don't miss any announcements.

All required and optional forms for participating in MC2 can be found here. New students have four forms they must complete to participate. Returning students, note that we have a new "Student Behavior Agreement" that we are asking all students to complete. Also, CPS students in 5th-8th grade can complete a form that gives MC2 acccess to your test scores and math grades--this is optional, but it helps us evaluate our program and report to our sponsors, and is thus greatly appreciated (and we need you to complete the form every year).


Students can register here for math circles within seven communities: Back of the Yards, Bridgeport, Little Village, Morgan Park, North Center, Old Town, and the University of Chicago. Each of these circles has different age ranges and meeting dates. Please go to our Locations Page to see which grade levels, dates, times, and locations best fit you. If you are new to MC2, we also recommend our FAQ page, which can help you determine which program level to choose.

Returning students with good attendance from the previous quarter are automatically given spots in our programs if they complete their registration prior to the priority deadline/lottery run. Other students enter a lottery and are in a pool, with priority given to public school students in Chicago, but open to all 5th to 12th graders in Illinois. After the priority deadline any student can enroll for their session of interest until 4 days before the second session of the quarter. This is on a first come, first serve basis while space is available.

Join our mailing list to be sure to receive announcements about registration, meeting dates for sessions, and more! If you are new to math circles, you should also go ahead and create an account (see below). All Math Circles of Chicago sessions are free!

Tips for account creation

  • The student email address can NOT be the same as the parent address. You can leave the student email address blank.
  • Chances are 99% that your school is already on our school list. if you begin to type any part of your school's name it should appear in the drop down list.
  • Even if your child is in middle school, you must include their high school graduation year! For fall 2020:
    • 5th graders will graduate from high school in 2028
    • 6th graders will graduate from high school in 2027
    • 7th graders will graduate from high school in 2026
    • 8th graders will graduate from high school in 2025


  • 5th and 6th Graders should sign up for Haynes-5/6.
  • 8th graders, particularly those not currently in a high school Algebra 1 course, and all 7th graders should sign up for Brahmagupta-7/8.
  • 8th graders and above enrolled in an Algebra 1 or Geometry course should sign up for Cantor-A1/G
  • Students in 10th grade or above who have completed a Geometry course should sign up for Kovalevsky-A2/PC. Such students are also welcome to enroll in Cantor if they are new to math circles.
  • Students who have completed two years in Kovalevsky-A2/PC should sign up for Euler. We know some younger students are interested in participating in Euler because they are doing advanced course work at school--feel free to email us at info@mathcirclesofchicago.org to and tell us about yourself, and we can have a conversation about whether Euler is the appropriate choice for you.
