Lesson objective: Compare fractions to common benchmarks of 0, half, or 1.

This lesson helps to build procedural skill with comparing fractions to a benchmark fraction. A number line is used here because it highlights a fraction's distance from the benchmark. This work develops students' understanding that fractions can be compared to a benchmark, and then the benchmark can be used to compare two or more fractions.

Students engage in Mathematical Practice 5 (students use appropriate tools strategically) as they decide which tool, including mental skills, will help them compare a fraction to a benchmark. Students continue to work with number lines, area models, and mental skills as they use the benchmark fractions to compare other fractions.

**Key vocabulary:**

- benchmark
- denominator
- equivalent
- half
- numerator
