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:

- Briefly describe the rules of your puzzle (you can include an example). The class has had a chance to look at these puzzle before, so this serves as a reminder of the rules instead of a step-by-step training.
- 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 may use a PowerPoint or other presentation, or simply give your talk in front of the blackboard.
- 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, 12/9 and Thursday, 12/11.
*Your group must sign up for a presentation time before leaving class on 12/2.*
