In this lesson, students to subtract fractions with unlike denominators. They start subtracting unit fractions with unlike denominators by drawing models of equivalent fractions. For example, students solve 1/3 -1/4. Then they subtract non-unit fractions with unlike denominators by drawing and writing a model of equivalent fractions.
