Materials Needed

• Whiteboard and markers
• Worksheets with practice problems
• Calculators (for verification)
• Projector (optional, for demonstration)

Lesson Procedure

1. Introduction (5 minutes)

• Greet the students and introduce the topic of the day: 3-digit by 1-digit multiplication.
• Briefly explain the importance of multiplication in daily life (e.g., calculating costs, measuring, etc.).
• Engage students with a few quick questions to activate prior knowledge:
  • What do we know about multiplication?
  • Can anyone give a real-life example of multiplication?

2. Direct Instruction (10 minutes)

• Write a sample problem on the board: 234 x 5.

• Explain the steps for solving a 3-digit by 1-digit multiplication:

  1. Multiply the ones place (4 x 5 = 20). Write 0 and carry over 2.
  2. Multiply the tens place (3 x 5 = 15) and add the carry-over (15 + 2 = 17). Write 7 and carry over 1.
  3. Multiply the hundreds place (2 x 5 = 10) and add the carry-over (10 + 1 = 11). Write 11.
  4. The final answer is 1170.

• Emphasize the importance of lining up numbers correctly and keeping track of the carry-over.

3. Guided Practice (10 minutes)

• Distribute worksheets with similar multiplication problems for the students to work on.

• Example problems:

  • 345 x 3
  • 678 x 2
  • 521 x 4

• Walk around and provide assistance as students work through the problems, checking their understanding and providing feedback.

4. Independent Practice (5 minutes)

• Allow students to complete a few practice problems individually.

• Example problems for independent work:

  • 462 x 6
  • 715 x 7

• Encourage students to show their work and keep track of carry-overs.

5. Wrap-Up and Review (5 minutes)

• Ask several students to share their answers to the independent problems and explain their thought processes.
• Recap the key steps in performing 3-digit by 1-digit multiplication, and clarify any misunderstandings.
• Assign homework that includes a variety of 3-digit by 1-digit multiplication problems.

---

Assessment

• Observation of students during guided practice.
• Review of completed worksheets and independent practice problems.
• Homework will be collected and evaluated for understanding.

---

Extensions

For advanced students, provide problems that involve multiplying by larger 1-digit numbers or introduce word problems that require students to apply their multiplication skills in real-world scenarios.

Closing

Reinforce the lesson by emphasizing how multiplication is a vital skill that will be used in more complex math situations. Encourage students to practice regularly and offer help if they are struggling with the material.
