Adding & Subtracting Fractions Word Problems Lesson Plan

Introduction

As a hook, ask students if they have ever shared a pizza or a cake with friends or family and how they figured out how much each person could have. Use this real-life situation to spark interest in adding and subtracting fractions with like denominators. Refer to the last page of the guided notes for additional real-life examples and the FAQs below for further ideas on engaging students.

Use the first page of the guided notes to introduce the concept of adding fractions with like denominators. Walk through the key points including understanding that the denominator stays the same, and only the numerators are added together. Emphasize the idea that these fractions must refer to the same whole to be combined accurately. Use the embedded check for understanding to assess if students grasp how and why we add numerators while keeping denominators constant. Refer to the FAQ below for tips on how to address common questions such as why denominators don’t change and how to identify like denominators in problems.

Use the second page of the guided notes to introduce subtracting fractions with like denominators. Highlight that, similar to addition, the denominator remains the same while subtracting the numerators. Focus on strategies for solving word problems involving subtraction of fractions, such as identifying the whole, the parts taken away, and the remaining fraction. Use the check for understanding prompts to ensure students can differentiate between addition and subtraction word problems and correctly apply the method for subtracting fractions. Consult the FAQ below for guidance on responding to questions like how to handle subtraction when the fraction parts seem confusing or how to visualize the subtraction of fractions with like denominators.

Based on student responses during these guided notes sections, reteach specific concepts where students show difficulty, such as misunderstanding the role of the denominator or the steps to solve word problems. For classrooms with a wide range of proficiency levels, consider pulling small groups of students aside for targeted reteaching while having more advanced students begin working on the practice exercises included in the resource. This allows you to tailor instruction to individual student needs effectively.

Practice

Have students practice adding and subtracting fractions with like denominators using the color by code worksheet activity. Walk around to answer student questions.

Fast finishers can dive into the maze activity for extra practice. You can assign it as homework for the remainder of the class.

Real-Life Application

Bring the class back together, and introduce the concept of using fractions with like denominators in everyday situations, such as sharing food, measuring ingredients in recipes, or dividing time during activities. Explain how adding and subtracting these fractions helps solve real-world problems, like determining how much of a pizza is left after some slices are eaten or how much time is spent on different tasks. Refer to the FAQ for more ideas on how to teach it!
