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

In this lesson, students will practice subtracting fractions with like denominators and learn how to subtract fractions with unlike denominators by first making them into equivalent fractions. Prior Knowledge Required: Ability to find common denominators, create equivalent fractions, and solve fraction addition problems with both like and unlike denominators. Represent and solve fraction subtraction problems and understand the connection between the subtraction and addition of fractions. Students may treat numerators and denominators as different numbers in calculating.
