This powerpoint takes students through the step by step process of adding and subtracting fractions with unlike denominators. First, they must list multiples to find a common denominator and use them to generate equivalent fractions. There are lots of examples to practice just for this step. Then it adds on the next step of performing the operation and simplifying the solution. There are also lots of examples for students to practice along with solutions so students can check their work and monitor their progress. At all points throughout the process, a visual model is provided so students and teachers can connect back to what is being done to the fractions.
