To start, kids need each fraction to have the same number of parts (again, a “like denominator”). Select two bars and place them above and below your number line from 0 to 1 to determine the difference in shaded amounts.

In our lesson, we modeled the mixed numbers using fraction bars, subdivided the models using a common denominator, and regrouped an addend if necessary. Subtract fractions and simplify with line models or subtract fractions and simplify with circle models will give instruction and practice in subtracting fractions with unlike denominators.
