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). Â 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 groupâ€™s work with the rest of the class. Â 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). Â Give an explanation, and an example to demonstrate your conjecture.
- If you were able to prove your conjecture, give a proof. Â 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:

- YouÂ must include some kind of slides (you may also put work on the board): Â 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 Thursday, 12/5. Â
*Your group must sign up for a presentation time before leaving class on 11/21.*
