Grade 4 Mathematics

Course/Grade Level Description

By the end of the fourth grade student will have consolidated addition and subtraction of whole numbers, and will have done much in multiplication and division of whole numbers. Work in number also extends to fractions and decimal fractions, using limited sets of fractions as the basis for building meaning for equivalent fractions, addition, subtraction, and fraction as part of a set of objects. Work in measurement becomes more sophisticated with emphasis on units and conversion within systems of units. In order to allow for the development of Number and Operations, there are relatively few expectations in Geometry and Data and Probability in Grade 4.
