Students in grade 3 also begin to enlarge their concept of number by developing an understanding of fractions as numbers. Additional Mathematics: In Grade 4, students compare fractions with unlike numerators and unlike denominators, while continuing to broaden their understanding of equivalent fractions. In Grade 4, students build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers. In 4, students understand decimal notation for fractions, and compare decimal fractions. This work with fractions will continue in grades 5 and beyond, preparing the way for work with the rational number system in grades 6 and 7. Possible Organization of Unit Standards: This identifies additional grade-level standards within a given cluster that support the over-arching unit standards from within the same cluster. The table also provides instructional connections to grade-level standards from outside the cluster. Over-Arching Supporting Standards Instructional Connections Standards within the Cluster outside the Cluster 3.NF.1: Understand a fraction 1/b 3.G.2: Partition shapes into parts with as the quantity formed by 1 part equal area. Express the area of each part when a whole is partitioned into b as a unit fraction of the whole. For equal parts; understand a fraction example, partition a shape into 4 parts with a/b as the quantity formed by a parts equal area, and describe the area of each of size 1/b. part as of the area of the shape. 3.NF.2: Understand a fraction as a 3.NF.2a: Represent a fraction on a 3.MD.4: Generate measurement data by number on the number line; number line diagram by defining the measuring lengths using rulers marked represent fractions on a number line interval from 0 to 1 as the whole and with halves and fourths of an inch.
