MATH 2233 - Number Sense 3 Credits
Introduces the prospective elementary teacher to deductive reasoning, number theory, numeration systems (bases), the properties and arithmetic associated with each number system, and number theory.
Prerequisite: Completion of LAD 9111 Math Essentials with a grade of “C” or better, or eligible for enrollment in LAD 9082 Math Reasoning Review 2 or LAD 9072 College Algebra Review 2 based on placement test .
It is highly recommended that the student has already completed, or is concurrently enrolled in a college-level math class.
Course Level Objectives
Upon successful completion of this course the student will be able to:
1. Use technology to collaborate, solve problems, represent data, and present solutions.
(GEO 1, 3, 4)
2. Demonstrate professional characteristics through verbal and written communication, team collaboration, organization, neatness, and overall self-presentation. (GEO 1, 3, 4)
3. Develop and apply basic concepts of number theory, (e.g. prime numbers, composite
numbers, greatest common factor/least common multiple, explanation of mistakes)
4. Develop and apply proportional relationships and percent (e.g. unit-rate problems,
percent problems) (GEO 2, 3)
5. Develop and model the basic four operations (Addition, Subtraction, Multiplication, and
Division) and their properties on whole, natural, integer, and real numbers. (GEO 2, 3)
6. Compute with other number systems other than Hindu-Arabic numeration (e.g. Egyptian,
Babylonian, Roman) and describe the historical significance to current numerations (understand the place value system). (GEO 2, 3)
7. Use and explain function notation, and different types of function representations to solve equations, system of equations, and real word scenarios. (GEO 1, 2, 3)
8. Compare and analyze numerical models using mathematical reasoning, algebra and geometry, to identify patterns (e.g. Arithmetic, Geometric, Fibonacci), predict outcomes, and make decisions. (GEO 2, 3)
9. Build and interpret tables, graphs, charts, and diagrams to explain the connections between geometry and algebra. (GEO 2, 3)
