Learning Goal
Part of: Extend understanding of fraction equivalence and ordering — 2 of 2 cluster items
Compare two fractions with different numerators and different denominators
**4.NF.A.2**: Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

What you'll learn
- Compare two fractions with different numerators and different denominators by creating common denominators, then comparing the numerators
- Compare two fractions by creating common numerators, recognizing that when numerators are equal, the fraction with the smaller denominator is larger (because the pieces are bigger)
- Compare two fractions by reasoning about benchmark fractions — especially 1/2, but also 0 and 1 — to determine which fraction is greater without finding a common denominator
- Explain why fraction comparisons are valid only when both fractions refer to the same whole, and identify situations where different-sized wholes make a comparison invalid
- Record the result of a fraction comparison using the symbols >, =, or <, and justify the conclusion using a visual fraction model (area model or number line)
