NY Math Circle Workshop at Bard College for Middle School Math Teachers!

The New York Math Circle is running its 5th summer math workshop (the 4th time at Bard College). The theme of this summer’s workshop is “Surface Area and Volume”, and is a nice experience with Solid Geometry for teachers. This is of interest to teachers local to Bard, as the commuter discount on top of the public school teacher discount together drop the cost of the workshop to minimal.

The full announcement is below:

Summer Teachers’ Workshop

Click here to Register

To our fellow math teachers,

With the end of the school year in sight, you may be wondering what to do with yourself this summer. The answer is our Summer Teachers’ Workshop!

Summer Workshop 2013 at Bard College (July 29 – August 2)

This summer’s theme is “Volume and Surface Area.” We’re looking forward to helping participants deepen their content knowledge of Solid Geometry and enrich their math classrooms with challenging problems. The workshop is designed for middle school math teachers, but all math teachers are welcome.

Mathematical Program

The workshop features 24 contact hours of mathematics centered around Volume and Surface Area. Mornings consist of collaborative problem sessions, while the afternoon talks—led by NY Math Circle instructors and Bard math professors—enrich and extend.

The co-organizers of the workshop are Japheth Wood, executive director of the New York Math Circle and math professor in the Bard Master of Arts in Teaching program, and Justin Lanier, math teacher at Saint Ann’s School in Brooklyn, and math blogger at I Choose Math and Math Munch. Japheth and Justin have designed the workshop to address the following questions, and more:

  • How are surface area and volume defined, and what are the connections between them?
  • How are volume and surface area formulas (such as for prisms, cones, and spheres) established?
  • What is the history of the subject, from Euclid and Archimedes to the modern day?
  • What are some challenging (yet accessible) problems, as well as hands-on math activities that will inspire our students and enrich our math classrooms?
  • How does this topic connect to the mathematics in high school and beyond?

For more information and to register for the workshop visit: http://www.nymathcircle.org/workshop
Public School Teachers: The Math for America discount for public school teachers drops the cost for the week (including room and board) from $445 to just $295. A letter from your principal is required.

Commuters: Local teachers save $150 for not requiring a dorm room for the week. But you still get everything else, including meals!

PD and Graduate Credit: Upon completion, you will receive a certificate and a letter documenting 24 math contact hours. With the approval from your principal, this can count as PD. You can also earn 2 graduate credits from the Bard MAT Program (a separate processing fee applies) by documenting how this workshop enriches your classroom over the following year.

Entertainment and Arts offerings
Independent of our workshop, the arts are alive at Bard College this summer. We’ve cleared the schedule on Wednesday afternoon for you to explore. You could choose to attend a 3pm performance of Oresteia by Sergey Taneyev, go for a hike, or discover other treasures that the area has to offer.
Our closing meal on Thursday evening will be at the Spiegeltent: a choice of classic summer fare — including burgers and brats from the grill, fresh salads, gourmet ice cream, and handcrafted beers and wines from the Hudson Valley region. Vegetarian options available, of course. Dinner transforms into performance, with Spiegeltent’s Thursday Night Live! Musicians Imharhan and Mamadou Kelly perform Music of Mali. “A captivating combination of traditional and contemporary West African sounds. The rumble and grit of Saharan nomads with electric guitars.”

We’re looking forward to seeing you at Bard College this summer!

Paper Plate Polyhedra – December 2012 Circle

Here are some pictures of our activity from December, 2012: Paper Plate Polyhedra. It’s amazing what you can do with a simple paper plate! A tip if you’re rushing out to buy paper plates: the cheaper the better for this one. The super fancy and durable plates don’t fold so well.

The Mathematics of Chalk

Dear Math Circlers,

Our monthly math circle is finally here! Please join on Saturday, May 11, 2013, from 1-3pm at the Kingston Library (55 Franklin Street, Kingston, NY), where we’ll combine our math enrichment activities with the library’s annual Chalk Walk. After our initial computations upstairs in the Community Room, we’ll leave behind the tomes, manuscripts and books, and head outside to the library’s beautiful garden exterior, to decorate the surrounding sidewalk. It’s the Kingston Library’s annual Chalk Walk, so we won’t be the only ones.

                   

As always, we feature mathematical puzzles and logical games, a sheet of insightful problems, and a hands-on math project that you can take home. This time, however, the hands-on project will be made with chalk, and you’ll leave it on the sidewalk. You’re welcome to snap photos, though, and take those home.

The mathematical theme this month is an amalgamation of some special triangles and friendly fractals. What do Pascal’s Triangle and Sierpiński’s Triangle have in common? Who can produce the most stunning fractal in chalk? This email contains some fractal images that you might try out on Saturday, but feel free to bring your own.

See you on Saturday!

Please Bring:
* Sunscreen / Umbrella / Sunglasses
* Camera
* Extra chalk, although the library will provide plenty
* A bottle of water – stay hydrated!
* Your favorite fractal! Try a google search for inspiration.

3rd Annual kingston Library Chalk Walk
This Saturday from 12:30 PM to 3:00 PM
Artists of all ages and skill levels are invited to participate in our Third Annual Chalk Walk.
The Chalk Walk will showcase community artwork and foster self-expression!
Artists will be assigned a 2 1/2 by 2 1/2 foot space to create a design. Chalk will be provided.
There will also be prizes, music, and food.
The event is free and will be held rain or shine. It is a smoke-free event.
Japheth

P.S.: The Bard academic year is coming to an end, so this is your chance to say goodbye to your favorite Bard Math Majors, and wish them good luck after graduation.

Mathematician at the Bard Masters of Arts in Teaching Program
                   


P.S.: The intent of each session is to create a friendly and safe context for exploration and mathematical thinking. We provide games and puzzles that help build mathematical intuition and logical thinking, a hands-on activity that results in a mathematical artifact to take home, and a sheet of math problems that features challenges at the middle school level.

Our activities are designed with middle school students in mind, but everyone is welcome.

January 2013 Update

Dear Bard Math Circle Community,

In November last year the Bard Math Circle offered the AMC 8 Math Competition for the first time, and had a fantastic turnout. Forty eight middle school students from around the area came to Bard College for this national exam, and worked on 25 mathematical problems in a 40 minute period.

The problems were challenging far beyond what students normally encounter in school: the median score was 9 problems correct (there was no penalty for a wrong answer or for guessing). For some this was a humbling experience (but not a humiliating one, I hope). There was a excitement about sharing solutions at our December math circles, and a lot of learning going on.

The AMC 8 Results are in!

According to the official report on the exam, there was one perfect score at Bard, by Sanath Kumar, who traveled to Bard from Westchester County with his family. Sanath was 9 years old at the time of AMC 8, and has since turned 10. He is in grade 6 at Our Montessori School. Congratulations, Sanath, and thanks for taking the contest at Bard College!

The next highest scores were:

  • Michael Liu, a student at Bailey MS in Kingston, grade 8. 
  • Katie Houston, a student at Miller MS in Kingston, grade 7.
  • Twins Erik Simon and Henry Cowherd of Ichabod Crane MS in Valatie, both grade 7.
A hearty congratulations to every student who took the exam! You learned some math along the way, and had fun doing it. For links to nicely written solutions, please see previous posts. 
If you would like a printed solution packet (while they last), then come by a math circle for a copy. If you’d like to know your score, please send a friendly email to bardmathcircle@gmail.com or stop by the next math circle meeting in Kingston on February 9.

The Parent Survey

While the middle school students were taking the exam their parents filled out a survey. The results were very positive (which is called a selection bias in statistical studies) but gave lots of useful information towards future programming.
There was interest in:
  • a more sustained math circle experience, such as, a 10-session semester program or summer day program. 
  • math circles at other libraries and as an after-school program at schools around the area.
  • volunteering for the Bard Math Circle.
Please follow our blog (bardmathcircle.blogspot.com) and our email announcements for information on future initiatives based on the survey. Thanks for filling out the survey, parents!

Alcumus for online learning

As an informal first step towards a more sustained math circle experience, I invite those math circle students who are focused on solving challenging problems to sign up for Alcumus, a free online problem system offered by the Art of Problem Solving. Alcumus has over 5,000 challenging math problems with full solutions, and is great for student practice. If you’re interested in helping me try out this system, please do the following:
  1. Open a free account on the Art of Problem Solving website, www.artofproblemsolving.com.
  2. If you are under 13 years old, you will be directed to print out the COPPA form for your parents to fill out and send in. This is important, so please do it, even though it will take longer.
  3. Log into Alcumus by clicking on the link in the top navigation menu. Try some problems.
  4. Email me with your Art of Problem Solving name so I can add you to the Bard Math Circle course.
  5. Start solving! I will seek ways to connect your online work with our Kingston Library meetings, while not detracting from everyone’s mathematical experience, even if they are not problem-focused.
If you have trouble getting started on the system, please email me, and I’ll try to help.
The Alcumus system is open to anyone, so once we get it going, it will be fun to invite friends, siblings, parents and teachers.
Here’s to our math circles in 2013!

Museum of Math : First Impressions

I have never been so hyper coming from a museum in my life! Today I went to the new Museum of Math in New York City and boy did I have a blast. The exhibits lend themselves to a variety of topics ranging from Emily Noether’s work on noncommutative algebra (simplified with a bird in a bowl) to a visual representation of a statistical distribution using a smaller version of the game Plinko from The Price is Right. I was thoroughly entertained and informed. There’s so much to math that lends itself to beautiful things and unique interpretations, this museum does that well. If you ever have the opportunity to go see it, I highly recommend it. It’s still a new museum so I expect more exhibits will be on their way.

If you want a virtual tour of the place check out this link

For information about the Museum of Math and their programs, check out their website http://momath.org/

For now, I’m FREEZING! I’m going to read a math book and make a mug of hot cocoa. Stay warm and we’ll see you soon!

AMC 8 Solutions

The AMC 8 Solutions have been published on the AMC website. But the real fun is happening at the Art of Problem Solving resource wiki, where you can already read nicely written solutions.
If you kept a record of the answers you submitted, you can calculate your informal score (out of 25). How did you do?
My informal score is 23. I had a lot of fun working on these problems (without a time constraint) during the week after the AMC 8, while riding around on the NYC subway, shuttling between appointments. I missed problems 21 and 22, mainly because I didn’t read carefully what was being asked. On the other hand, it’s been a long time since I was in middle school. I think I would also have really enjoyed them way back then!
Please leave a comment about your experience with the AMC 8. What were your favorite problems? Do you have a solution you’re proud of? What did you miss, and why? If you can join us on Saturday, December 8th, we’ll share some solutions at the math circle meeting at the Kingston Library, 1pm-3pm.
See you there!
