The math department provides learning experiences that prepare students to achieve the following outcomes:

- demonstrate an understanding of a wide variety of fundamental mathematical concepts and the nature of mathematical proof
- read mathematical literature and communicate mathematical ideas effectively both orally and in writing, using appropriate language, good notation, and sound mathematical reasoning
- apply mathematical knowledge from one branch of mathematics to another as well as to other disciplines
- use appropriate technology
- have good problem-solving skills, including the ability to formulate problems, solve them and interpret solutions
- understand the historical and cultural framework of mathematics and the relationship of mathematics to other sciences and to the needs of society in general

In addition, teaching majors will be able to:

- gather, analyze and interpret data in an unbiased manner
- demonstrate that they know and can apply the national and state standards for mathematics instruction

The mathematics department sponsors an honors program for motivated students. An honors student must satisfy the following criteria:

- Maintain a GPA of at least 3.5 in mathematics courses.
- In each mathematics course the student takes after acceptance into the program, the student may be given one or more special assignment not expected of other students in the class (e.g., non-routine problems that might be too much for the typical student in the class).
- Complete a senior thesis under the guidance of some member of the department, based on an in-depth study or research project conducted with a department faculty member or at a Research Experience for Undergraduates (REU) program (or both). The senior thesis must be approved by the mathematics faculty.
- Give an oral presentation of the senior thesis to mathematics faculty and students on campus.
- Complete MATH 325 Modern Algebra I and MATH 330 Real Analysis I.

The student must submit a letter to the department chair applying to the honors program no later than the beginning of their second-to-last semester before graduation. The student must give a written proposal detailing their plans for a senior thesis no later than the end of the fourth week of their second-to-last semester. Both the oral presentation and the senior thesis must be completed no later than four weeks before the date of graduation – a paper or electronic copy of the thesis must be submitted to the chair of the department by this time. The department faculty will give decisions on the application to the program, the senior thesis proposal, and the final decision of whether or not to award honors promptly after each step in the process.

Students’ initial placement in mathematics courses is determined on the basis of their high school record. This list may be helpful:

- With one year algebra and one year of geometry or less, the recommended mathematics option is MATH 105 Exploring Mathematics.
- With algebra, geometry and higher algebra, options are:
