Georgia 4.NR.4.3
The Standard
Compare two fractions with different numerators and/or different denominators by flexibly using a variety of tools and strategies and recognize that comparisons are valid only when the two fractions refer to the same whole.
Georgia's K-12 Mathematics Standards · Solve real-life problems involving addition, subtraction, equivalence, and comparison of fractions with denominators of 2, 3, 4, 5, 6, 8, 10, 12, and 100 using part-whole strategies and visual models.

What This Standard Means
What Students Need to Do
- Students compare two fractions using benchmarks, equivalent fractions, number lines, area models, or reasoning about numerators and denominators. They explain the comparison and check that both fractions describe the same-sized whole.
What Mastery Looks Like
- A student can choose an efficient strategy, use <, >, or = correctly, and justify the comparison with a model or equation. The student notices when different-sized wholes make a comparison invalid.
Common Misconceptions
- Students may compare only numerators or denominators, such as claiming 3/8 is greater than 2/3 because 3 is greater than 2. They may also assume a larger denominator means a larger fraction or compare fractions of different-sized wholes.
How to Assess It
- Exit ticket: Ana shaded 5/8 of one paper strip, and Ben shaded 2/3 of an equal-length strip. Compare the fractions, justify your answer, then explain why equal-length strips matter.
Lesson moves
Ways to Teach It
Give pairs equal-length fraction strips; have them compare six fraction pairs and record each result with <, >, or =.
Ask, “Is 3/5 always greater than 1/2?” and have students write a claim supported by a drawing.
Prepare cards showing fractions with denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100; play Fraction War.
Compare recipe amounts such as 3/4 cup and 2/3 cup, then explain which amount is greater using a benchmark.
