Multiplying Fractions and Mixed Numbers Word Problems Lesson Plan

Introduction

As a hook, ask students if they have ever needed to share something like a pizza, a chocolate bar, or a carton of juice evenly among their friends. How would they figure out how much each person gets if they only had a part of a whole? Refer to the real-life math application page at the end of the guided notes as well as the FAQs below for additional ideas and examples.

Use the first page of the guided notes to introduce multiplying a fraction by a whole number. Walk through the key points: what it means to multiply a fraction by a whole number, how to interpret the word problems, and the step-by-step process for solving them (e.g., multiply the numerator by the whole number while keeping the denominator the same, then simplify if necessary). Refer to the FAQ below for a detailed walk-through, including common misunderstandings and questions about fraction multiplication.

Use the second page of the guided notes to introduce multiplying mixed numbers by whole numbers. Guide students through converting mixed numbers to improper fractions, multiplying by the whole number, and then converting back to mixed numbers if needed. Emphasize strategies for interpreting and solving word problems involving mixed numbers and discuss how to check answers for reasonableness. Refer to the FAQ below for ideas on how to handle common student questions and errors.

Based on student responses during the checks for understanding, reteach any concepts where students struggle, such as converting between mixed numbers and improper fractions or simplifying answers. For classes with varying proficiency, consider pulling small groups for targeted reteaching while more advanced students begin the practice exercises included later in the resource.

Practice

Have students practice multiplying fractions and mixed numbers by whole numbers using the color by code and maze activities. Walk around to answer student questions.

Fast finishers can dive into the problem sets 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 multiplication of fractions by whole numbers in real-life situations such as cooking or baking, where recipes often need to be adjusted for more servings. Discuss how understanding this math skill helps in measuring ingredients correctly. Refer to the FAQ for more ideas on how to teach it!
