Videos, examples, solutions, and lessons to help Grade 4 students learn to 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.

Common Core: 4.NF.2

### Suggested Learning Targets

• I can explain that comparing 2 fractions must refer to the same whole.
• I can compare 2 fractions by reasoning about their size.
• I can compare 2 fractions by creating equivalent fractions with a common denominator (if needed).
• I can order fractions using <, >, and = and justify the comparison.

Comparing To The Benchmark 1/2 (4.NF.2)

Compare and Order Fractions
Examples:

1. Write 3/8, 1/4, and 1/2 in order from least to greatest.
2. Write 4/6, 5/12, and 2/4 in order from greatest to least.
3. Samantha and her two friends Julia and Richie had a relay race. The table shows their finish times. In what order did Samantha, Julia, and Richie finish the race?
