Course Information
General
- Class Meets: MWF 9:00-9:50 in RH 316
- Instructor:
- Anneke Bart (http://math.slu.edu/~bart)
- Office: Ritter Hall 115
- Office Hours: MW 1-2 and Tue 9-10 or by appointment.
- Email: barta@slu.edu
- Prerequisite: 3 years of high school mathematics or Math 120 (College Algebra).
Grading
- 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. Being late twice or leaving early counts as an absence.
- Homework will be due weekly. 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.
- Exams. I give makeup exams only for severe and documented reasons.
- Exam 1: TBA
- Exam 2: TBA
- Final: Monday December 14. Time: 8:00 - 9:50. Place: RH 316
- Grading is on a straight scale, with 90%,80%,70%,60% guaranteeing A,B,C,D.
Grading is weighted as follows:
- Exams: two @15% each
- Homework and in-class work: 20%
- Tessellation Project: 10%
- Cathedral Poster Assignment: 10%
- Final: 30% (the final is comprehensive)
Textbooks
The main text for this course is the Math and the Art of MC Escher online book, at http://math.slu.edu/escher
One traditional textbook is required for the course:
- D. Schattschneider, Visions of Symmetry. H. Abrams 2004. (The paperback 1990 edition is also acceptable).
Honesty
Students are expected to be honest in their academic work, as per the 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.
Homework Assignments
On Friday August 28, Homework #1 is due:
Read Visions of Symmetry pg. 1-15.

Schedule
This tentative schedule will give you some idea of what topics to expect. As the course develops, adjustments will be made if necessary.
Week 1: Introduction, Symmetry
August 24 - 28
- Monday: Introduction to the course; First topic is "Symmetry"
- Wednesday: Do the Symmetry of Stars and Polygons Exploration and Rozette Symmetry Groups with Kali Exploration.
- Friday: Rotational and Reflectional Symmetry in Escher’s Sketches and Symmetry, Escher and Architecture Exploration
Week 2: Symmetry, Isometries, and Frieze Patterns
August 31 - September 4
- Monday: Introduction to Frieze patterns. Do exploration Frieze Marking Exploration and Frieze Names Exploration
- Wednesday: Quiz and start on new homework.
- Friday: Do Identifying Frieze Patterns Exploration
(Fri September 4 Last day to drop without a "W")
Week 3: Wallpaper Patterns
September 7 - 11
- Monday: Labor Day: Official University Holiday
- Wednesday: An introduction to wallpaper patterns Tessellations, a first look Exploration
- Friday: Went over border patterns and discussed some problems from homework 2.
Some points to remember:
- Start homework early, so you have time to ask questions.
- Anything on homework or explorations can show up on an exam.
- Always explain your answer. You will need to explain yourself on any exam to get full credit, but apart from that it is a good idea to explain how you arrived at your conclusions. It will be easier to assign partial credit if more information is given, and it will also be easier for the instructor to give feedback in case there is some confusion.
Week 4: Wallpaper Patterns
September 14 - 18
