# Teaching 4.NF.A.2 – Compare Two Fractions with Different Numerators and Different Denominators

## Number & Operations – Fractions – 4th Grade

**Extend understanding of fraction equivalence and ordering.**

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.

**Teacher Notes**

I know how to create equivalent fractions.

I know the larger the denominator, the smaller the partitions of the whole.

I know comparisons of fractions are only valid if the whole is the same size.

I can record the result of the comparison using symbols >, =, or <, and justify my conclusions.
