# MATH 180 - Number Theory for K-8 Teachers

5 Credits
This course guides students in examining the ideas and reasoning underlying the real number system and its associated operations. Students will also study the reasoning behind common and unfamiliar computation algorithms; physical, visual, and symbolic representations of numbers; percentages and proportions; problem solving; and will practice communicating mathematical ideas. Recommended for prospective or practicing K-8 teachers.

Student Learning Outcomes
Summarize mathematics standards relevant to K-8 students from a variety of sources, such as national (e.g., NCTM) or state standards.

Apply knowledge about features of our number system to analyze (1) other number systems and (2) common error patterns that arise when children are learning our number system.

Describe the concept of a whole number as well as relationships between them (order, divisibility, factorization, and common factors/multiples).
.

Describe the purpose of basic operations on whole numbers and the concepts underlying these basic operations.

Represent decimals, fractions, integers, ratios (rates), percentages, and proportions in multiple ways.

Compare and contrast decimals, fractions, and integers with whole numbers and each other.

Compare and contrast ratios (rates), percentages, and proportions.

Compare and contrast the standard algorithms for computing with decimals, fractions, and integers with those for whole numbers.

Analyze common error patterns in students’ computations and demonstrate how alternative algorithms can reduce those errors.
