Arizona's College and Career Ready Standards
AZ.3.NF. Number and Operations – Fractions (NF)
3.NF.A. Understand fractions as numbers.
3.NF.A.1. Understand a fraction (1/b) as the quantity formed by one part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
3.NF.A.2. Understand a fraction as a number on the number line; represent fractions on a number line diagram.
3.NF.A.2.c. Understand a fraction 1/b as a special type of fraction that can be referred to as a unit fraction (e.g. 1/2, 1/4).
3.NF.A.3. Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
3.NF.A.3.c. Express whole numbers as fractions, and recognize fractions that are equivalent to whole numbers.
3.NF.A.3.d. Compare two fractions with the same numerator or the same denominator by reasoning about their size. Understand that comparisons are valid only when the two fractions refer to the same whole. Record results of comparisons with the symbols >, =, or <, and justify conclusions.
AZ.3.G. Geometry (G)
3.G.A. Reason with shapes and their attributes.
3.G.A.2. Partition shapes into b parts with equal areas. Express the area of each part as a unit fraction 1/b of the whole. (Grade 3 expectations are limited to fractions with denominators b = 2,3,4,6,8.)
