## Course Information

### General

• Class Meets: MWF 12:00-12:50 in RH 323
• Instructor:
• Prerequisite: 3 years of high school mathematics or Math 120 (College Algebra).

• Attendance is required. You will have in-class work to be done in groups. One unexcused absence is allowed. Six absences will cause you to lose two letter grades. I only excuse absences when presented with official documentation.
• Homework will be due most weeks. Your work should be neat, legible, and stapled. Cooperation is good, but write up results separately. Late homework is always accepted, but I will not write comments and will automatically give a score of 5 (out of 10) if the work is of reasonable quality.
• Art Projects. There will be four art projects over the course of the semester, which will be drawn or painted. You will need some decent quality paper for these, better than printer paper or posterboard. You may also want drawing materials, such as ink pens, colored pencils, or pastels.
• Exams. I give makeup exams only for severe and documented reasons.
• Midterm: Friday, October 16
• Final exam: Wednesday, December 9, 12-1:50pm
• Grading is on a straight scale, with 90%,80%,70%,60% guaranteeing A-, B-, C-, D respectively. Grading is weighted as follows:
• Homework: 20%
• Attendance and in-class work: 20%
• Art Projects: 30%
• Exams: 30%

### Textbooks

The main text for this course is the Math and the Art of MC Escher online book, at http://math.slu.edu/escher

It is highly recommended that you purchase a copy of J. Locher, Magic of M.C. Escher. H. Abrams 2000.

### Honesty

This course is goverened by the Academic Honesty Policy of the College of Arts & Sciences. Plagiarism, cheating and dishonesty will be reported to the dean and may result in probation, expulsion, or worse.

### Disabilities

In recognition that people learn in a variety of ways and that learning is influenced by multiple factors (e.g., prior experience, study skills, learning disability), resources to support student success are available on campus. Students who think they might benefit from these resources can find out more about:

Course-level support (e.g., faculty member, departmental resources, etc.) by asking your course instructor. University-level support (e.g., tutoring/writing services, Disability Services) by visiting the Student Success Center (BSC 331) or by going to http://www.slu.edu/success. Students who believe that, due to a disability, they could benefit from academic accommodations are encouraged to contact Disability Services at 314-977-8885 or visit the Student Success Center. Confidentiality will be observed in all inquiries.

Course instructors support student accommodation requests when an approved letter from Disability Services has been received and when students discuss these accommodations with the instructor after receipt of the approved letter.
