- Monday: Meet as a group.
- Discuss issues of common interest proposed by students.
- Discuss common issues with homework assignments.
- Give an overview of the week to come.

- Wednesday: Meet with me in smaller groups (about half the class).
- Work on problems in small groups of about 4 students.
- Discuss any issues of common interest.

- Friday: Office hours/discussion (not mandatory).
- Discuss questions of common interest proposed by students.

**Technology: **You will need:

- A computer or tablet to watch instructional videos and to participate in class meetings on zoom.

- There will be five midterm exams during class time and a final exam.

**Meeting times:**

- C2: MWF 10-10:50.
- X1: MWF 12-12:50

**Required Text: **Introduction to Abstract Mathematics (Donaldson and Pantano)

- Course packet available at the Illini Union Bookstore.
- We will cover all of the topics in this book and will cover other topics during the last month of class.

**Course Description:**

This is an introduction to mathematical language, rigorous mathematical thinking, fundamental mathematical structures, and methods of proof. Topics include logic, set theory, induction, equivalence relations, functions, number theory, cardinality, and convergence.

**Grades: **The final grade will be computed based on these percentages:

- Highest four midterm exams: 11% each. Lowest midterm exam: 6%
- Final Exam: 20%
- Homework: 20%
- In-class work, attendance and participation: 10%
- We will not "curve" the final averages down.
- For example, if your final average is 80% then your final grade will be some sort of "B".
- The precise function which assigns a letter grade to each percentage will be determined at the end of the course.
