Lesson Plan: Multiplication of 3-Digit Numbers by 1

Subject: Mathematics
Year Group: 9
Duration: 30 minutes

---

Objectives

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

1. Understand the concept of multiplying 3-digit numbers by 1.
2. Demonstrate proficiency in performing multiplication of 3-digit numbers by 1.
3. Apply the knowledge in practical examples.

---

Materials Needed

• Whiteboard and markers
• Worksheets with multiplication problems
• Multiplication table reference charts
• Calculators (optional)

---

Introduction (5 minutes)

Begin the lesson by engaging the students with a quick recap of multiplication principles, as they relate to single-digit numbers. Explain that multiplying by 1 maintains the value of the number:

• Example:
  • ( 1 \times 3 = 3 )
  • ( 1 \times 5 = 5 )

Introduce the concept that this principle extends to larger numbers, including 3-digit numbers.

---

Direct Instruction (10 minutes)

1. Explain the Concept:

   • Write a 3-digit number on the board, for example, 456.
   • Show the multiplication operation:
     ( 456 \times 1 = 456 )

2. Demonstrate Multiple Examples:

   • Calculate the following on the whiteboard:
     • ( 123 \times 1 )
     • ( 789 \times 1 )
     • ( 345 \times 1 )

3. Key Point:

   • Emphasize that multiplying any number by 1 results in the original number. This reinforces the identity property of multiplication.

---

Guided Practice (10 minutes)

Distribute worksheets containing a variety of multiplication problems where students multiply different 3-digit numbers by 1.

Example Problems:

1. ( 234 \times 1 )
2. ( 512 \times 1 )
3. ( 804 \times 1 )
4. ( 927 \times 1 )

Encourage students to share their answers with a partner and discuss any difficulties they encounter.

---

Independent Practice (5 minutes)

Have students complete the remaining problems on the worksheet independently. Circulate the room to offer assistance as needed.

Additional Problems:

5. ( 600 \times 1 )
6. ( 415 \times 1 )
7. ( 777 \times 1 )

---

Conclusion and Questions (5 minutes)

Wrap up the lesson by revisiting the key concepts learned:

• Review the importance of the identity property in multiplication.
• Invite students to ask any questions or clarify doubts.

Encourage students to reflect on real-world applications of this concept, such as when calculating total quantities in different contexts.

---

Homework

Assign a homework task where students must find five 3-digit numbers in their daily life (e.g., prices, page numbers) and write a short paragraph about how multiplying these numbers by 1 reinforces their understanding of multiplication.
