Lesson 12 Concept Development

Problem 1: Reason about the size of a fraction compared to 1/2.

Problem 2: Plot points on a number line by thinking about fractions in relation to 0, 1/2, or 1. Compare the fractions.

Problem 3: Use the benchmarks 0, 1/2, and 1 to compare two fractions without using a number line. Lesson 12 Benchmarks
