MATH 6551 - Understanding Number Systems and Operations


(3 sem. cr.) Understanding rational numbers is the foundation for understanding other critical mathematic concepts and their application to everyday life. In this course, middle-level mathematics teachers explore exciting ideas to help students determine appropriate operations for solving problems and becoming more proficient in working with factors, multiples, fractions, decimals, percents, and negative numbers. Teachers develop problem-based activities to engage students in using common algorithms and other mathematical reasoning and sense-making strategies for adding, subtracting, multiplying, and dividing rational numbers. Strategies for estimation and using the number line to represent and solve problems are also provided in this course.
