Getting ready to subtract fractions? This lesson reviews how to subtract like denominators and teaches students how to subtract unlike denominators. The focus is on understanding the process and reasoning behind each step.
Fractions can be challenging when taught in an abstract way. That’s why this unit invites learners to engage with fractions and mixed numbers in very visual and concrete ways using number lines, tape diagrams and area models. Students will learn different strategies to practice identifying and generating equivalent fractions.
Does chaos ensue when your students subtract like mixed numbers and the larger fraction has a lesser numerator? Using this lesson plan, teach your class how to overcome this tricky obstacle: When having like denominators isn’t enough!
Encourage students to explain their processes when converting from a mixed number to an improper fraction, and back again. Use this lesson on its own or as support to the lesson Single Strategy for Adding and Subtracting Mixed Numbers.
Continue to build on your students' understanding of unlike denominators by asking students to justify their answers of fraction subtraction. Use this lesson with the Subtracting Fractions with Different Denominators lesson.
