# MATH 322 Syllabus

### Elementary Theory of Arithmetic II

Revised: September, 2014 (Kathy Jaqua)

Course Description

A study of mathematical topics including number theory, operations, fractions, and proportional reasoning necessary for teaching elementary and middle grades students. Three semester hours.

Prerequisite: Math 321.

Student Learning Goals and Objectives

MATH 322 is a C2 (Mathematics) Liberal Studies Course. The learning goals for C2 Courses are that:

• Students will be introduced to applications of mathematics in daily experience.
• Student learning will be focused on the development of conceptual understanding rather than computational drill.
• Students will complete a project requiring a mathematical analysis of observations, such that a significant portion of the student project will be statistically based.

Student Learning Objectives Specific to Math 322

1. Learn to use words, symbols, and techniques of mathematics with precision so as to communicate concepts and ideas correctly and clearly.
2. Experience the satisfaction of mathematics discovery, which stimulates curiosity, initiative, confidence, and interest in mathematics.
3. Develop patterns of reasoning which enable one to investigate unfamiliar situations.
4. Develop understanding and appreciation of the structure of the number system, elementary number theory, and proportional reasoning.
5. Develop an ability to organize mathematics experiences as a means of discovery rather than presentations of a fixed set of facts and procedures.
