3.NR.2: Represent and compare fractions in multiple ways using part-whole relationships.

Represent and compare fractions in multiple ways using part-whole relationships.

3.NR.2.1Identify unit fractions as the quantity formed by one part when a whole is partitioned into 2, 3, 4, 6, or 8 equal-sized parts. Express each part as a unit fraction of the whole.3.NR.2.2Represent fractions from 0 to 1 using concrete, set, area, and linear models, and write them in standard form and word form. Limit denominators to 2, 3, 4, 6, and 8.3.NR.2.3Express whole numbers as fractions and identify fractions that are equivalent to whole numbers. Limit denominators to 1, 2, 3, 4, 6, and 8.3.NR.2.4Compose fractions between the whole numbers 0 and 5 using unit fractions. Record the composition as a mixed number or fraction greater than 1. Limit denominators to 2, 3, 4, 6, and 8.3.NR.2.5Recognize two fractions are equivalent. Limit denominators to 2, 3, 4, 6, and 8, and fractions should be limited to fractions between 0 and 1.3.NR.2.6Compare two fractions with the same numerator or same denominator based on the same size whole by reasoning about their size. Use the symbols for is equal to (=), is less than (<), or is greater than (>). Limit denominators to 2, 3, 4, 6, and 8, and fractions should be limited to fractions between 0 and 1.
