## Catalog Description:

**MATH 210 Discrete Mathematics A**

Careful study of the foundations of mathematics needed for study of mathematics
at the advanced undergraduate level. Topics from logic, set theory, proof
techniques, elementary number theory , mathematical induction, functions,
relations, basic combinatorics. Credit will not be given for both MATH 210 and
CSIT 241.

Prerequisite: MATH 121 or MATH 123.

**Rationale:**

This course provides a careful study of the foundations of undergraduate
mathematics. It serves as a bridge from the more concrete, procedure-driven
courses at the freshmen level to the more abstract, proof- and
application-oriented courses at the junior and senior level. The course
emphasizes the development of the student’s ability to generalize and abstract
mathematical concepts – to read, speak, and write proper mathematics – including
the ability to read, understand, and do proofs. As such, most universities now
require a course such as MATH 210 for all mathematics majors.

The most recent curriculum recommendations from the Committee on the
Undergraduate Program in Mathematics of the Mathematical Association of America,
(CUPM Curriculum Guide 2004) stipulate that courses designed for mathematical
sciences majors should ensure that students:

•Develop mathematical thinking and communication skills.

•Progress from a procedural/computational understanding of mathematics to a
broad understanding encompassing logical reasoning, generalization, abstraction,
and formal proof;

•Become skilled at conveying their mathematical knowledge in a variety of
settings, both orally and in writing.

•Develop skill with a variety of technological tools.

•All majors should have experiences with a variety of technological tools, such
as computer equations .html">algebra systems , visualization software, statistical packages, and
computer programming languages.

•Provide a broad view of the mathematical
sciences.

•All majors should have significant experience working with ideas re presenting
the breadth of the mathematical sciences. In particular, students should see a
number of contrasting but complementary points

of view: continuous and discrete; algebraic and geometric; deterministic and
stochastic; theoretical and applied;

•Majors should understand that mathematics is an engaging field, rich in
beauty, with powerful applications to other subjects, and contemporary open
questions.

MATH 210 will help students achieve all of these desired outcomes.

In addition, a MATH 210 is particularly relevant for those students intending
to teach mathematics, and it is a required course for each of the fol lowing
majors :

•Early Childhood and Childhood Education with a Mathematics Concentration

•Mathematics/Middle Childhood Education

•Mathematics/Adolescence Education

In its recent report, The Mathematical Preparation of Teachers, the
Conference Board of the Mathematical Sciences (CBMS) states that, to be
well-prepared to teach the new Standards-based curricula, elementary, middle,
and high school mathematics teachers need to develop a “deep understanding” of
school mathematics concepts and procedures. Such knowledge will enable teachers
to “assess their students’ work, recognizing both the sources of student errors
and their students’ understanding of the mathematics being taught. It will also
enable teachers to “appreciate and nurture the creative suggestions of talented
students” and allow teachers to see the “links between different mathematical
topics and make their students aware of them.”

In its recommendations for elementary teacher preparation, the report goes on
to note that teacher candidates “must believe that mathematics is about ideas
that make sense, rather than a collection of motiveless rules” and that “among
the obstacles to improved learning at the elementary level, not the least is
that many teachers were convinced by their own schooling that mathematics is a
succession of disparate facts, definitions, and computational procedures to be
memorized piecemeal.” Recognizing this, mathematics courses for prospective
elementary teachers must begin by “helping teachers make meaning for the
mathematical objects under study – meaning that was often not present in their
own [education] – and only then moving on to higher orders of generality and
rigor.” MATH 210 is designed to be in line with these precepts, as well as with
the report’s call for helping elementary teacher candidates develop a deep
understanding of mathematics that “includes acquiring a rich network of concepts
extending into the content of higher grades; a strong facility in making,
following, and assessing mathematical argument; and a wide array of mathematical
strategies.”

As for prospective middle grades teachers, the CBMS report calls for courses
that “will strengthen these prospective teachers’ own knowledge of mathematics
and broaden their understanding of mathematical connections between one
educational level and the next.” It indicates that “discrete mathematics can
offer teachers an opportunity to explore in depth many of the topics they will
teach.”

Similarly, as concerns the preparation of high school mathematics teachers,
the CBMS report notes the increasing importance of discrete mathematics in the
curriculum, and the increasing use of technology to facilitate connections
between discrete mathematics and the more traditional high school topics in
algebra, analysis, and geometry. It recommends that, to be well-prepared to
teach such curricula, prospective teachers need:

In the area of Algebra and Number Theory:

•Understanding of the properties of the natural , integer, rational, real, and
complex number systems;

•Understanding of the ways that basic ideas of number theory and algebraic
structures underlie rules for operations on expressions , equations, and
inequalities;

•Understanding and skill in using algebra to model and reason about real-world
situations;

•Ability to use algebraic reasoning effectively for problem solving and proof in
number theory, geometry, discrete mathematics, and statistics.

In the area of Geometry and Trigonometry :

•Understanding of the nature of axiomatic reasoning and the role that it has
played in the development of mathematics, and facility with proof.

In the area of Functions and Analysis:

•The ability to translate information from one representation (tables,
graphs , or formulas) to another;

•The ability to use functions to solve problems in calculus, linear algebra,
geometry, statistics, and discrete mathematics.

The National Council of Teachers of Mathematics, in its Principles and
Standards for School Mathematics, has identified five content standards and five
process standards that “specify the understanding, knowledge, and skills that
students should acquire from prekindergarten through grade 12.” MATH 210 is
directly relevant to the following NCTM standards:

•Number and Operations Standard

•Understand numbers, ways of representing numbers, relationships among
numbers, and number systems.

•Understand meanings of operations and how they relate to one another.

•Algebra Standard

•Understand patterns, relations, and functions.

algebraic symbols .

•Problem Solving Standard

•Build new mathematical knowledge through problem solving.

•Solve problems that arise in mathematics and in other contexts.

•Apply and adapt a variety of appropriate strategies to solve problems.

•Monitor and reflect on the process of mathematical problem solving.

•Reasoning and Proof Standard

•Recognize reasoning and proof as fundamental aspects of mathematics.

•Make and investigate mathematical conjectures.

•Develop and evaluate mathematical arguments and proofs.

•Select and use various types of reasoning and methods of proof .

•Communication Standard

•Organize and consolidate mathematical thinking through communication.

•Communicate mathematical thinking coherently and clearly to peers,
teachers, and others.

•Analyze and evaluate the mathematical thinking and strategies of others.

•Use the language of mathematics to express mathematical ideas precisely.
