Learning Objectives

By the end of this lesson, students will be able to:

• Multiply whole numbers by fractions using visual fraction models and repeated addition.
• Use key vocabulary related to fractions and multiplication accurately.
• Demonstrate understanding of fraction multiplication through a real-world themed task (restaurant setting).

---

Materials Needed

• Whiteboard and markers
• Fraction strips or fraction circles
• Visual model printouts depicting restaurant items (pizza slices, drinks, dessert portions)
• Student mini whiteboards and markers
• Cartoon restaurant theme visuals (menus, orders)
• Key vocabulary cards
• Formative assessment worksheet (short exit ticket)

5E Instructional Model Lesson

---

Engage (5 minutes)

Purpose: Hook students’ attention and activate prior knowledge.

• Begin with a fun cartoon restaurant sketch projected onto the board. (Example: cartoon waiter brings a pizza and says, “You want 3 whole pizzas, but each pizza is cut into 4 slices. How many slices do you get?”)
• Ask: “How would you find out how many slices of pizza there are in total if you had 3 whole pizzas, each divided into 4 slices?”
• Quick discussion to elicit prior knowledge about multiplication as repeated addition and concepts of fractions.

---

Explore (7 minutes)

Purpose: Students investigate multiplying a whole number by a fraction through hands-on activities.

• Present an order from the cartoon restaurant menu:
  “A customer orders 2 whole pizzas. Each pizza is cut into 1/4 pieces. How many 1/4 pieces are there in all?”
• Give students fraction strips or circles representing 1/4.
• Students model repeated addition: 1/4 + 1/4 + 1/4 + 1/4 = 1 whole pizza; now multiply 2 × 1/4 visually by combining two sets of 1/4 slices.
• Use visual models on mini whiteboards to draw and represent the multiplication problem: 2 × 1/4
• Encourage students to express multiplication as repeated addition and verify results with models.

---

Explain (7 minutes)

Purpose: Teacher clarifies concepts and introduces vocabulary explicitly.

• Use the cartoon restaurant to introduce and define key vocabulary with visuals:
  Fraction, numerator, denominator, multiply, product, repeated addition, whole number
• Write a multiplication equation on the board:
  3 × 2/5 = ? (Use slices of cake or pieces of sandwich to visualize).
• Explain how multiplying whole numbers by fractions can be shown as repeated addition of fractions (3 times 2/5) or using area models.
• Demonstrate step-by-step how 3 × 2/5 = (2/5) + (2/5) + (2/5) = 6/5 or 1 whole and 1/5.
• Emphasize how the multiplication of a whole number and fraction differs slightly from whole number multiplication and the importance of visual support.

---

Elaborate (7 minutes)

Purpose: Provide students with a challenging, real-world problem-solving activity applying their understanding.

• Hand out a restaurant “menu” worksheet with cartoon pictures of food items divided into fractional parts (e.g., drinks in 1/3 cups; sandwiches in halves).
• Pose problems like:
  • “If one customer orders 4 drinks and each drink is 1/3 cup, how much drink do they get altogether?”
  • “A table orders 5 sandwiches, each cut into 1/2 pieces. How many half-pieces are there?”
• Students use visual models and repeated addition on their mini whiteboards to solve.
• Walk around and confer with students as they work, providing guiding questions.
• Encourage writing number sentences that match the visual models (e.g., 4 × 1/3 = 4/3 cups).

---

Evaluate (4 minutes)

Purpose: Formative assessment to check understanding and reinforce learning.

• Exit Ticket:
  • One short question: “Draw and solve: 3 × 1/4 (using a pizza slice model).”
  • Write the multiplication expression and repeated addition equivalent.
• Collect exit tickets to review mastery for next lesson planning.
• Quick verbal recap: ask 2-3 students to explain what they learned and share key vocabulary.

---

Differentiation and Extensions

• For advanced students: Challenge with improper fractions and mixed numbers (e.g., 7 × 3/2).
• For students needing support: Provide additional visual aids and guided practice with smaller numbers.

---

Reflection & Teacher Tips

• Use the cartoon restaurant theme throughout the year to revisit fraction concepts and keep engagement high.
• Incorporate technology (if possible) such as fraction applets for virtual manipulation and reinforcement.
• Pause often to check for understanding, using student-friendly language to explain fraction multiplication.

This lesson places strong emphasis on connecting abstract fraction multiplication to relatable, visual, and repeated addition strategies within a familiar, imaginative restaurant context — all aligned tightly with Common Core standards for 5th grade fractions.
