3.NF.A.3

Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.

Understand equivalent fractions as two regions equally shaded or two points at the same position on the number line. Compare fractions as <, >, =, using the same methods.

Compare fractions having the same numerator, denominator, or both. Start with manipulatives and pictures, then gradually move away from them. Find equivalent fractions using the length model, fraction sectors, and number lines.
