Lesson Plan: Long Division
Subject: Mathematics
Grade Level: 5
Duration: 30 minutes
Objective
Students will understand the process of long division and be able to divide multi-digit numbers by single-digit numbers.
Materials Needed
- Whiteboard and markers
- Paper and pencils for each student
- Long division worksheets
- Interactive division game (optional)
Introduction (5 minutes)
- Hook: Begin with a relatable question, such as "If you had 24 pieces of candy to share with 3 friends, how many pieces would each friend get?"
- Discussion: Allow students to verbalize their thoughts on how they would approach the problem. Introduce the concept of long division as a method to solve such problems systematically.
Direct Instruction (10 minutes)
-
Explain the Process:
- Write a division problem on the board (e.g., 144 ÷ 12).
- Explain each step of long division:
- Divide: How many times does the divisor (12) go into the first digit/group of digits of the dividend (144)?
- Multiply: Multiply the divisor by the quotient obtained.
- Subtract: Subtract the result from the dividend.
- Bring down: Bring down the next digit from the dividend.
- Repeat: Continue the process until all digits have been brought down.
-
Example: Solve the problem 144 ÷ 12 step by step on the whiteboard, clearly emphasizing each stage.
Guided Practice (10 minutes)
- Group Activity: Provide each student with a worksheet containing similar long division problems (e.g., 156 ÷ 12, 225 ÷ 15).
- Collaborate: Allow students to work in pairs to solve the problems while circulating the room to offer support and guidance.
Independent Practice (5 minutes)
- Worksheet: Distribute a short worksheet with 3 long division problems for each student to complete individually.
- Monitor: Encourage students to use the steps discussed in class and ask questions if they get stuck.
Conclusion (5 minutes)
- Review: Recap the long division steps and answer any final questions.
- Preview: Briefly discuss how long division will be useful in real-life scenarios, such as dividing resources or calculating averages.
Homework
Long Division Practice: Complete the following problems:
- 420 ÷ 5
- 672 ÷ 8
- 399 ÷ 3
Homework Answers
- 420 ÷ 5 = 84
- 672 ÷ 8 = 84
- 399 ÷ 3 = 133
Assessment
Use the students' completed worksheets and homework to assess their understanding of long division.
Extensions
For students who grasp the concept quickly, challenge them with more complex division problems or introduce long division with remainders. For those who need extra support, provide one-on-one assistance or additional practice problems with smaller numbers.
