This assignment is the final deliverable for your project (worth 10 points). It is an individual, not a group, assignment and should be submitted by email, not on the OpenLab.
The Semester Project consisted of a number of related activities and assignments – before you begin writing, please take a look at the list and click each of the links to remind yourself of all the parts of the project.
Assignment (Due before your final exam – Tuesday, December 20th). SUBMIT BY EMAIL, NOT ON THE OPENLAB. This is your chance to reflect on the Semester Project, and to describe your contributions to the major group activities. Please respond to all of the following.
Part 1 (200 words minimum). Write one or two paragraphs reflecting on the Semester Project, from the initial assignment (“OpenLab #5: Bridges and Walking Tours“) through to the final presentations. You can use the following questions to guide your writing if you wish (or you can respond in whatever way you wish):
Part 2. Describe your personal contributions to the final two major group assignments, the group paper and the group presentation. Do you think that you were an equal contributor in your group? Be as specific as you can.
The last significant group assignment for your semester project is a group presentation (there will be one more individual assignment, a reflection on the process). I’ll put the details here, followed by an outline of the grading criteria (the presentation is worth 20 points total).
Semester Project – Group Presentation
This is your chance to share your group’s work with the rest of the class. Each group will give a 5-8 minute presentation, including the following items:
Keep in mind the following:
Grading Criteria (20 points total)
_____ points (4 possible). Basics. Stay within time limits (5-8 minutes). All group members participate.
_____ points (6 possible). Conjecture. Conjecture is written down. Explanation and example are provided.
_____ points (7 possible). Proof of conjecture or proof process description.
_____ points (3 possible). Challenge the class. At least one puzzle is given for the class to work on on their own.
____ points TOTAL (20 possible)
Assignment. Your goal for today is to refine the conjecture you decided on during your last class meeting. Some things to consider:
GROUP CONJECTURES SUBMITTED AT END OF CLASS TODAY:
In his essay A Mathematician’s Lament, Paul Lockhart says “A good problem is something you don’t know how to solve.” This is quite different from most of the “problems” that appear in our mathematics education. In the past weeks, you’ve all spent some time individually and in groups working on such problems, in the context of graph theory (“Bridges and Walking Tours”).
As a group, write an account of your experiences working on your puzzle/problem. You should include the following elements:
I will be meeting with each group next Thursday, November 10th, in class. Please be in touch with your other group members before then! Be prepared to discuss your progress so far – at the very least, you should be able to describe how you are dividing up the work of the paper among your group.
The first draft of this assignment is due in class on Thursday, November 17. Each group should submit one paper, of no less than 1500 words. You may decide as a group how to divide up the work. Be aware that you will be asked at a later time to describe your own specific contributions as well as those of each group member.
The final draft of this assignment is due in class on Thursday, December 1.
REGARDING SEMESTER PROJECT: As you may recall from the Course Description, the semester project is worth 10% of your overall grade. The project consists of a number of interrelated activities (many of which have already been completed) – complete details can be found on the Project Overview & Deliverables page. The group paper assigned here forms a significant portion of the project.
Your assignment for the next week is to try to prove the conjecture that your group created in class on Tuesday, 10/14/15. You must spend at least 90 minutes working on this. Trying to prove something can consist of many different activities, such as the following (you do NOT have to do all of these things – you can choose how to spend your time – they are provided for inspiration only).
As you work, keep track of what you are doing, thinking, and feeling (this is metacognition – an idea that discussed way back in OpenLab #2). What did you do during the time you spent? Did you create any puzzles? Did you solve puzzles? Did you change your mind about whether the conjecture is true or false? Did you have any new ideas about how to prove the conjecture? Did you have any ideas that you gave up on? How did you feel as you worked – were you frustrated/confused/happy/depressed? Why? Did your mood change along the way?
Assignment (Due Thursday, 11/3/15): Submit a journal of your efforts in the comments below. Your response should be at least 300 words. Describe what you did during the 90 minutes you worked, and express in some way what you were thinking and feeling during the process. Your response can include puzzles (use sketchtoy.com) or other work you did along the way.
Extra Credit. Respond to a fellow student’s comment. Did you do similar things? Different things? Do you have any suggestions for them? Be kind.
Written work, Due Thursday, October 27, in class:
Chapter 6 p.116: 3,4,5,8,9
Chapter 7 p129: 5, 9, 10, 12
**NOTE: this assignment is due on Thursday, instead of on Tuesday, because we have our second exam on Tuesday.

In 2002, a mathematician named Paul Lockhart wrote an essay called “A Mathematician’s Lament,” a passionate criticism of mathematics education in America. It has become widely known among mathematicians and mathematics educators – not everyone agrees with everything he says (though many do), but everyone seems to have something to say about “Lockhart’s Lament,” as it is called. For this week’s assignment, you will read a short excerpt (three pages) from his essay and respond to the prompts below.
Assignment (Due Friday, 10/14/16). Your assignment has three parts:
First, read the section titled “Mathematics and Culture” (pages 3-5) in Lockhart’s essay, (click here). If you’re interested, I encourage you to read more, starting at the beginning – but this is not required.
Second, write a response to what you read and post it in the comments below. Your response should be at least 300 words. Your response should represent your own thoughts and opinions on what you read, and can include responses to any or all of the following:
Third, and most important, I want you to write down a conjecture about the Bridges and Walking Tours game, and bring it with you to class on Friday 10/14 (do NOT post it here). Consider Lockhart’s example of a triangle drawn inside a rectangle. He described the process of playing around with this picture, until he arrives at the basic idea for calculating the area of a triangle. He contrasts this with a traditional math class, in which the formula is given to students without providing them any opportunity to explore the problem on their own. The bridges and walking tours game is a little like the triangle-rectangle picture – it’s fun to play around with, but you may not be sure what the point is. You’ve had a chance to play with it a bit, and try some different challenges. Now what? Your job is write down a conjecture (a guess!) or a question about your game. If you could have one question answered about your game, what would it be? If you wanted to be a master of your game, and be able to solve any challenge that was given to you, what would you need to know? Write down a conjecture or question about your game, and bring it with you to class on Friday 10/14 (do NOT post it here).
Here is an example: Let’s imagine that you have just been introduced to the game Tic-Tac-Toe. After playing it for a while, you might come up with one of the following:
Conjecture: The person who goes first always wins.
Question: Is the corner the best move, or the center?
Conjecture: It’s impossible to win, no matter who goes first.
ps. Paul Lockhart retired from being a first-rate research mathematician in order to teach math at a private elementary school here in Brooklyn, Saint Ann’s School, where he says “I have happily been subversively teaching mathematics (the real thing) since 2000.”
