Hi everyone,

I enjoyed reading the drafts of your papers very much – thanks! I’ve sent feedback to each group, copying all group members, by email. If you didn’t receive anything, please let me know and I’ll resend it (I used the email addresses that I pulled from cunyfirst at the beginning of the semester, but I’m not sure if they are all accurate).

If you have questions about any of my comments, please let me know. As a reminder, your final draft is due in class on Thursday, December 3 (by email or hard copy).

Regards,

Prof. Reitz

Hi everyone,

Two comments on the Exam 3 Review sheet:

- In class, I proposed a strategy for solving problem #2, which was to break into cases based on the remainder when n was divided by 4. While I believe this strategy will work, it is simpler to simply look at the cases “n is odd” and “n is even”. Despite my comments in class, this method really will work (can anyone explain why?)
- It looks like the answer for problem #7 in the answer key was all wrong – I’m not sure what happened. In any case, I’ve updated it, so it should now be correct.

Both of these corrections were due to a diligent student who will remain nameless (but, in fact, it was Irania – nice work!).

Let me know if you find anything else,

Prof. Reitz

Exam 3 will take place on Tuesday, November 24th. The review sheet and answer key have been posted on the Handouts page.

Best,

**WeBWorK **– Assignment 6, due Tuesday, December 1st

**OpenLab** – none

**Project **– first draft of group paper due in class on Thursday, 11/19

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:

- State your conjecture (this should be written down, either on a slide or on the board). Give an explanation, and an example to demonstrate your conjecture.
- If you were able to prove your conjecture, give a proof. If not, describe briefly some of the ideas you had and strategies you tried while trying to prove it.
- Give the class at least one puzzle to work on on their own – a challenge!
- Give the audience a chance to ask questions (either during the presentation, or after).

Keep in mind the following:

- You must include some kind of slides (you may also put work on the board): PowerPoint, Google Slides, Prezi.com, LaTeX Beamer, or other.
- You may decide as a group how to divide up the work, but
*each group member must present something*to class. - 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.
- Presentations will be given at the beginning of class on Tuesday, 12/1 and Thursday, 12/3.
*Your group must sign up for a presentation time before leaving class on 11/19.*

**Grading Criteria (20 points total)**
