**Text**: *Topology of Surfaces*, L. Christine Kinsey, 2nd ed.
My plan is to cover a good part of the book.
What we actually cover will depend partly on the interests of the class.

**Goals of the course**: To give you a foundation in one of the fundamental areas of mathematics and and to promote your theorem proving skills.

**Homework Assignments**:
We will have weekly homework. The assignments will be posted here. I encourage you to discuss the homework problems, but you must write up your solutions individually.

**Quizzes**: Each Thursday we will have a short in-class quiz.

**Tests**: We will have three in-class hour exams.

**Final Exam**: We will use part of this time slot for our last
weekly quiz, and we may also need to use part of this time slot
to make up a class if we have to cancel a class.
The time slot is: 7:30 to 9:30 a.m., Friday, Dec. 14.

### Grade Scales, Averages and Semester Grades

There are three hour exams.
In addition, there are weekly quizzes and homework.
Your Semester Grade
is determined by averaging your grades on these items with the following
weights:

hour exams average 50 points each (drop lowest)
quiz average worth 100 points (after dropping lowest)
homework average worth 100 points
Total 300 points

**Course Evaluation**: The Department of Mathematics Course Evaluation Form will be available through your Blackboard account during the last two weeks of class. You'll get an email when the form becomes available. Evaluations are anonymous and instructors do not see any of the responses until after final grades have been submitted. Evaluations are important---the department uses evaluations to improve instruction. Please complete the evaluation and take the time to do so thoughtfully.

**SSD**: Students with disabilities are encouraged to contact the instructor for a confidential discussion of their individual needs for academic accommodation. It is the policy of the University of Nebraska-Lincoln to provide flexible and individualized accommodation to students with documented disabilities that may affect their ability to fully participate in course activities or to meet course requirements. To receive accommodation services, students must be registered with the Services for Students with Disabilities (SSD) office, 132 Canfield Administration, 472-3787 voice or TTY.

**Departmental grading appeals policy**: Students who believe their
academic evaluation has been prejudiced or capricious have recourse for
appeals to (in order) the instructor, the departmental chair, the departmental
appeals committee, and the college appeals committee.
