Multiplying Fractions Worksheet
Begin with a brief review of what fractions are and how they represent parts of a whole.
Pose a question: "If I have 2/3 of a pizza and I want 4 times that, how much pizza will I have?"
Show a quick video on the Smartboard that introduces multiplying fractions visually using pizza slices (2 minutes).
Introduce the steps for multiplying a fraction by a whole number.
Write the problem 2/3 × 4 on the board and guide students through the process:
Multiply the numerator by the whole number (2 × 4 = 8).
Keep the denominator the same (denominator = 3).
The result is 8/3, which can be simplified to 2 2/3.
Use fraction strips to demonstrate visually.
Highlight key points like keeping the denominator unchanged and simplifying improper fractions.
Hand out fraction strips and ask students to solve 3 problems with your guidance:
1/4 × 5
2/5 × 3
3/7 × 2
Walk around the room to ensure all students are engaged and on track.
Students complete 5 problems in their math workbooks (p. 45-46):
1/3 × 4
2/6 × 5
3/5 × 3
5/8 × 2
7/9 × 4
Encourage students to simplify their answers.
Review answers as a class and ask volunteers to explain their reasoning.
Summarize the key steps to multiply fractions by whole numbers.
Provide a quick exit ticket: "What is 3/4 × 5?"
Formative: During guided practice, observe student participation and correct understanding.
Summative: Multiplying Fractions Worksheet (10 questions) to be completed at home and submitted the next day for grading.
Complete the Multiplying Fractions Worksheet for additional practice (due tomorrow).
Challenge problem: "If 4/5 of a ribbon is 3 times longer, how long is the ribbon now?"
For struggling learners: Provide extra help during independent practice, use larger fraction visuals, and allow peer assistance.
For advanced learners: Challenge them with word problems involving multiplying fractions by mixed numbers or whole numbers.
For visual learners: Use fraction strips and the Smartboard throughout the lesson to visually reinforce concepts.
What went well: Students were engaged during the warm-up and used fraction strips effectively.
What to improve: Spend more time on simplifying fractions, as some students struggled with this step.
