You and your students will enjoy this PPT lesson! It's an Adding Fractions with Unlike Denominators Made Easy lesson. The multiple steps involved are demonstrated one step at a time using area models. This method makes the process easy to understand, plus a worksheet is included for practice.

Student involvement occurs throughout the lesson. They should have paper and pencil ready. The PPT begins with a visual demonstration of the necessity of having like units in order to add numbers. Then a problem is solved through modeling that ask students to re-create each step on notebook paper. Students will next do a Guided Practice with immediate fly-ins feedback after each step.

The visual demonstration with student re-creation leads to better comprehension. Your students will feel proud of themselves when they see that they UNDERSTAND and CAN USE this strategy to add fractions with unlike denominators. A practice worksheet is also included that can be used to your liking.

Common Core Standard: MCC5.NF.1 Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.) Use equivalent fractions as a strategy to add and subtract fractions.
