Unit 1, Lesson 3# Representing and Adding Fractions with Unlike Denominators

Massachusetts Department of Elementary and Secondary Education 60 min(s)

Students have had experience with adding fractions with like denominators in the previous grades. In this lesson, students will practice adding fractions with like denominators and learn how to add fractions with unlike denominators by first making them into equivalent fractions. In this lesson one denominator is manipulated. As you plan, consider the variability of learners in your class and make adaptations as necessary.
