Understand fractions as numbers.

NC.3.NF.1 Interpret unit fractions with denominators of 2, 3, 4, 6, and 8 as quantities formed when a whole is partitioned into equal parts;

• Explain that a unit fraction is one of those parts.
• Represent and identify unit fractions using area and length models.

NC.3.NF.2 Interpret fractions with denominators of 2, 3, 4, 6, and 8 using area and length models.

• Using an area model, explain that the numerator of a fraction represents the number of equal parts of the unit fraction.
• Using a number line, explain that the numerator of a fraction represents the number of lengths of the unit fraction from 0.
• NC.3.NF.3 Represent equivalent fractions with area and length models by: Composing and decomposing fractions into equivalent fractions using related fractions: halves, fourths and eighths; thirds and sixths.
• Explaining that a fraction with the same numerator and denominator equals one whole.
• Expressing whole numbers as fractions, and recognize fractions that are equivalent to whole numbers.
