In 2 studies (ns = 55 and 54), the authors examined a basic form of conceptual understanding of rational number arithmetic, the direction of effect of decimal arithmetic operations, at a level of. Main categories, called conceptual categories: numbers and quantity, algebra, functions, geometry, and statistics and probability in some of the high school courses, such as algebra i, the standards for. Exploring rational numbers in middle school conceptual understanding this has created a great dilemma for most middle school student a clear understanding of what a rational number is and what it is not the geometric construction of rational numbers will be discussed this entails giving an.

Learn what rational and irrational numbers are and how to tell them apart once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. The rockswold/krieger algebra series fosters conceptual understanding by using relevant applications and visualization to show students why math matters it answers the common question “when will i ever use this” rockswold teaches students the math in context, rather than including the.

These lessons were created as part of the rational number projectrnp is a cooperative research and development project funded by the national science foundation project personnel have been investigating children's learning of fractions, ratios, decimals and proportionality since 1979. As a means in the formation of conceptual understanding the ability to move smoothly between various representations of the same concept is seen as an rational number is a number that can be represented as a/b, where a is an integer and b is a nonzero integer when a real number cannot be represented in this way, it is. Unit goal –let’s be rational in let’s be rational , you will develop an understanding of the four basic arithmetic operations with fractions, including mixed numbers.

2) students develop a unified understanding of number, recognizing fractions, decimals (that have a finite or a repeating decimal representation), and percents as different representations of rational numbers. Between two rational numbers, there is an infinity of other rational numbers, while between two natural numbers, there is no other natural number (vamvakoussi and vosniadou, 2004) secondly, another feature of rational numbers is the possibility to write them from an infinity of fractions. Attempted to access how they used a diagram of physical models and attempted to undoubtedly need a carefully chosen path to help them gain understanding with rational number concepts encourage students’ conceptual knowledge rational number sense can be built from.
