Versatile math practice formats designed for busy educators and parents.
💡 1. The Butterfly Method (Cross-Multiplication)
Multiply numerator 1 by denominator 2, and numerator 2 by denominator 1: for 2/3 vs 3/4, compare 2 × 4 = 8 and 3 × 3 = 9. Since 8 < 9, 2/3 < 3/4!
💡 2. Same Denominator Rule
When denominators are identical (e.g., 3/7 vs 5/7), the fraction with the larger numerator is larger (3/7 < 5/7).
💡 3. Same Numerator Rule
When numerators are identical (e.g., 1/3 vs 1/5), the fraction with the smaller denominator is larger because the pieces are bigger (1/3 > 1/5).
Worksheet Facts by Grade Level
| Grade Level | CCSS Standard | Target Fractions |
|---|---|---|
| Grade 3 | Compare two fractions with same numerator or denominator (CCSS.3.NF.A.3.D) | Like denominators and unit fractions within 6 |
| Grade 4 | Compare two fractions with different numerators and denominators (CCSS.4.NF.A.2) | Unlike denominators up to 12 with cross-products |
| Grade 5–6 | Order lists of 3+ fractions and mixed numbers (CCSS.5.NF.A.1) | Fractions and mixed numbers with denominators up to 16 |
Why Comparing Fractions Builds Proportional Reasoning
Comparing fractions with different numerators and denominators (CCSS.4.NF.A.2) is the foundational test of fractional number sense.
Students learn that a fraction represents both a value and a division ratio. Recognizing relative magnitude prevents common misconceptions like assuming $2/5 > 2/3$ simply because $5 > 3$.
Comparison Strategies by Grade Level
- Benchmark Fractions ($0, 1/2, 1$): Compare both fractions to $1/2$ (e.g., $3/8 < 1/2$ and $5/8 > 1/2$, so $3/8 < 5/8$).
- Common Denominator Method: Find the Least Common Multiple (LCM) of denominators and scale numerators.
- Cross-Product Method: Compare $a \times d$ with $b \times c$ for any pair $\frac{a}{b}$ vs $\frac{c}{d}$.

Frequently Asked Questions
Why does the butterfly cross-multiplication method work?
Cross-multiplying is just a fast way of giving both fractions a common denominator (b × d) and comparing the scaled numerators (a × d vs b × c) without writing out the bottom numbers.
How do you compare mixed numbers?
Compare the whole number parts first. If the whole numbers are equal, compare the remaining fractional parts using cross-multiplication.
